In this collaboration post between Cryptomedics and SmartOptions, we want to demystify the Bitmex Universe. This guide shall be the first stop for everyone, that wants to hop on the Bitmex train and learn how to use this great piece of a FinTech platform. Going Bitmex is not easy for beginners, especially if you don’t come from Forex trading or other derivates offering leverage, on top of that Bitmex has some specialties you should know about. The major part of this post has been provided by the Cryptomedics Margin Channel, we at SmartOptions chimed in and added our secret sauce for you and explain the common pitfalls that one can face with the platform. Let’s dive into it and learn on how to ride that beast.
BitMex stands for Bitcoin Mercantile Exchange and it’s a platform designed for advanced currency traders in the industry. Experienced traders can get up to 100 times leverage in contracts and shorting, which increases the chances of making it big profits or losses.
Advanced traders are more comfortable with higher risk and that’s why this platform is so popular with them.
BitMex only trades in Bitcoins, which means profits and losses are made in Bitcoin even if you use altcoin to finance trading. This platform isn’t beginner friendly and not suitable for everyone.
Mind you: invest only what you can afford to lose!
Let’s take a look at the trading interface
This interface might be cluttered to some and we suggest to remove all the information you don’t use. We like it pretty simple and just have the charts and the positions box there. Don’t fall in love with the order books too much, especially newbies can be distracted by fake walls.
This is the board to set up your position:
By placing an order on Bitmex, you are buying their “contract”, not BTC. Each contract is worth $1. As you can see in the picture, the quantity is $100. This quantity is the BTC contract. $100 quantity equals 100 contracts.
What means to “go long”, what means to “go short”?
When a trader is in a long trade, they bought “Buy” contracts for an asset and are hoping the price will go up.
Crypto traders often will use the terms “buy” and “long” interchangeably. Similarly, some trading software has a trade entry button marked “buy,” while others trade entry buttons marked “long.” The term often is used to describe an open position, as in “l am long in Ripple,” which indicates the trader currently owns tokens of Ripple.
Traders often say they are “going long” or “go long” to indicate their interest in buying a particular asset. If you go long on 1,000 tokens of EOS at $10, the transaction costs you $10,000. If you are able to sell the coins or tokens at $10.20, you will receive $10,200, and net a $200 profit, minus commissions. This type of scenario is preferred when going long. The alternative is that the price drops. If you sell your holdings at $9.90, you receive $9,900 back on your $10,000 trade. You lose $100, plus commission costs.
When you go long, your profit potential is unlimited since the price of the asset can rise indefinitely. If you buy 100 tokens at $1, that token could go to $2, $5, $50, $100, etc. Your risk is limited to the token going to zero. In the example above, the largest loss possible is if the token price goes to $0, resulting in a $1 loss per share.
Day traders in short trades sell assets before buying them and are hoping the price will go down.
They realize a profit if the price they buy it for is lower than the price they sold it at. “Shorting” is confusing to most new traders since in the real world we typically have to buy something in order to sell it. In the financial markets, you can buy and then sell or sell then buy.
Day traders often use the terms “sell” and “short” interchangeably. Similarly, some trading software has a trade entry button marked “sell,” while others have a trade entry buttons marked “short.” The term short often is used to describe an open position, as in “I am shorting XLM,” which indicates the trader currently has a short position in XLM. Traders often say I am “going short” or “go short” to indicate their interest in shorting a particular asset.
Similar to the example of going long, if you go short on 1,000 tokens of EOS at $10, you receive $10,000 into your account, but this isn’t your money yet. Your account will show that you have – 1,000 contracts, and at some point, you must bring that balance back to zero by buying at least 1,000 tokens. Until you do so, you do not know what your profit or loss on your position is.
If you are able to buy the contracts at $9.60, you will pay $9,600 for the 1,000 tokens, but you originally received $10,000 when you first went short, so your profit is $400, minus commissions. If the token price rises and you buy the tokens back at $10.20, you pay $10,200 for those 1,000 tokens and you lose $200, plus commissions.
When you go short, your profit is limited to the amount you initially received on the sale. For example, if you sell 100 tokens at $5, your maximum profit is $500 if the token goes to a price of $0. Your risk, though, is unlimited since the price could rise to $10 or $50, or more. The latter scenario means you would need to pay $5,000 to buy back the tokens, losing $4,500.
Shorting, or selling short, allows professional traders to profit regardless of whether the market is moving up or down, which is why pro traders usually only care that the market is moving, not which direction it is moving.
Do you see the white bar below the sell/short box? When that bar is full, your position will be filled immediately upon placing the order and vice versa for the buy/long box. On a side note, if your order is filled immediately, you are a fee taker not fee maker. You are fee taker when you “take” the price which is set by the exchange and fee marker when you place the limit price. For more info on Bitmex fees, click here.
This is the formula to calculate the profit on Bitmex when you purchase a position. This formula can be both applied to short and long positions. You can also use Bitmex calculator to compute the profit/loss and liquidation price.
Profit = (1/ entry price – 1/closing price) * position size.
Example: You open a long position at $6000 with 1000 contracts. Then BTC price rises to $7000.
Profit = (1/6000 – 1/7000)*1000 = 0.02 BTC
This is the expense to open the position. Cost can be reduced by increasing the leverage. The higher the leverage, the lower the cost, thus pushing the liquidation price closer to your order’s price.
When you tick in this box, you order will be hidden instead of appearing in the order book. You can input the amount of contracts you want to buy.
The post-only limit order option makes sure the limit order will be added to the order book and not match a pre-existing order. If your order matches a pre-existing order, your post-only limit order will be canceled. This is usefull if your entry price is not yet in sight, you are basically casting out your line to fish an upcoming order which does not yet exist in the order books. Once it is there you can catch this fish immediately and get your order executed with the highest possible maker rebate.
By using reduce-only order, you will not be able to spend more than you have in your position. Example: you open a 300 XBT long position at 6100, you then process to calculate taking profit at 6200 and want to put more 300 XBT in the position. However, because you have already ticked in the reduce-only box, the short order will not be executed more for than 300 XBT. Under some circumstances, it can be helpful to uncheck the reduce-only checkbox – for example, you expect a certain price to be reached, followed by a reversal/drop. This can be especially interesting when the charts show much wick action. Example: You expect the price to reach the resistance at 6,800 followed by a hard rejection. You own 1000 contracts long to the price target of 6,800. In the case you want to turn your long position into a short position at this price, you would place a sell order for 2000 contracts and uncheck Reduce-Only the reduce-only checkbox. This is called a buy-sell order and will result in a new short position as your sell 1000 contracts more than you own. With the box ticked, it would ignore the additional 1000 contracts and just sell your existing 1000 long contracts.
When you click into this box, 3 different types of commands appear will appear.
GoodTillCancel allows you to fill your position separately. Example: you want to a buy a long position with 1000 contracts at 6000 but there is only 500 contracts in the market. Your position will be filled 500 contracts without closing your order. ImmediateOrCancel allows you to partially fill your position. Any unfilled contract will be canceled when you choose this feature. FillOrKil allows you to fill your order immediately only if there are enough contracts in the market for your position.
This is the most important part of this guide. Please understand it carefully before trading. In theory, leverage allows you to borrow your money from the exchange to increase your position size. Example: you borrow $1000 to increase your position size from $1000 to $2000 then return the loan after you close your position. When BTC goes up 10%, you will also make more profit and vice versa.
No leverage profit: $1000 * 10% = $100
Leverage profit: $2000 * 10% = $200
However, Bitmex is different. By using leverage, you won’t open the position with a bigger size but you open the position with lower cost. As you can see on the left side, the cost to open a position is much higher compared to the right side thus minimizing your fees. However, the higher the leverage, the closer the liquidation price to your limit price. Therefore, we recommend you to use 2x or 5x leverage when you first start trading. Otherwise, remember to set your leverage to 1x. Cross leverage can become equal to 100x leverage and is very dangerous if you don’t know what you are doing. In fact, Cross burns newbie accounts day by day.
On the top right of the trading interface, you can see the funding rates.
Understanding the funding feature on Bitmex is difficult. Funding rates can be positive and negative. Basically, you can say a negative funding rate pays you interest if you are long and takes equity from your position if you are short. Versa vice with a positive funding rate. The interval between each funding is 8 hours, this is the point of time where the account becomes charged and credited.
Let’s move on to the limit price. What is it? The limit price is the price that your position will be filled once the market price reaches the limit price. In the picture above, you can see that there are three tabs for 3 different types of order: limit order, market order and stop market order. We will explain each type of order one by one. Important to know is, the underlying concept: If you place a limit order it won’t get executed immediately (in the most cases), but once a particular price is reached. This ensures the fees rebate. A market order costs lots more of fees and is executed immediately against the order books. So if trader A has a limit sell order 6,456K and you put a market order buy at that price he sells his shorts against your longs.
What is limit order? In limit order, you place the order hoping that the price will hit the limit price. When it hits the limit price, your position will be filled. However, it depends on the market whether your order is fully filled or not. In this case, you are a fee maker, not fee taker. Placing limit orders in total has a very low fee which is why it is favored by traders.
What is a market order? As you can see, in comparison to limit order, you cannot set limit price which means if you click on buy or sell market, the order will be filled immediately In this case, you are a fee taker, not fee maker because you did not “make” the price, you “take” the price which is set by the exchange. For every market order, the fee is much higher compared to limit order. Therefore, we recommend you to use limit order instead of market order. Market orders are mainly for FOMO or if you can see a major breakthrough and you want to get in as fast as possible.
Stop market order
Stop market order is used for setting stop-loss. Example: You have a long position at $6000 and you want to set a stop-loss at 5990. Open the stop market order, type in the stop price 5990, an order will be opened and filled at the same time when the market reaches that price. On a side note, close on trigger is an advance feature of Bitmex. When you check this box, all the amount in your position and open-order will be reduced, canceled upon the trigger.
Stop-limit order is similar to stop market order. However, there is one difference, stop price triggers limit price. Example: you set stop price at $6000 and limit price at $5900 for your long position. The $5900 order can only be triggered once the market price comes down to $6000. Here the order becomes activated and visible in the order book (if you have “hidden” unchecked). From now other traders can pick up your order. However, setting up your stop-loss is not advisable and a common pitfall. On rapid price movements, far below the stop-limit order, it is likely that your order will not get filled – which means your stop-loss is useless. Hence, we recommend to use the (more expensive) market orders for your stop-loss as the likeliness of getting it filled is much better.
In other words, it’s a price interval. By using this type of order, you can protect your profit. Example: You open a long position at $6000, BTC rises from $6000 to $6010, a stop-loss order will be placed at $6005. However, if it keeps rising, the stop-loss order will be increased accordingly and always be placed $5 less than the current price.
Take profit-limit/ Take profit market
These 2 orders are the opposite versions of stop-limit and stop market order and used to take profit once a certain price is reached. Take profit limit orders are meant to be used if you exepect a longer more ongoing movement in the preferred direction. Take profit market is mostly used if you want to take profit on spikes for example. Day traders use the market option to get sure their order get filled, swing traders might prefer the limit option.
This board shows you the current open orders including short and long orders.
This is the graphic version of order books. Basically, the buy/sell walls we know from other exchanges as well. Read more about them in this post about how to read buy/sell walls.
This is the chart for you to set up your trading strategies.
This is where you can see your current position. Let’s explain all the terms in this board. Symbol is the product of your position. Size is the amount of money you put in your position. The value indicates the worth of your position. Entry price tells you when your order is filled. Mark price is the last price of the product of your position. Liquidation price indicates at which price, your position will be liquidated by the exchange. Margin is your position after you used leverage. Unrealized PNL (profit and loss) is what your position has gained/lost right now if you would close it down at this very moment. Unrealised PNL is the amount of gain/loss that the exchange realizes. Unlike unrealised PNL, realised PNL is the real profit and loss after you close your position it shows how much you made or lost within the current trade with this instrument, but also shows earnings like from the fundng rate for example.
This is where can you see your open order(s). Let’s explore the terms. Symbol still the same like above. Quantity equals to Size in the open position board. Filled shows the amount of contracts that have been bought. Order value is the same as Size in the open position board. Fill price demonstrates the price which fills your position. It’s can be varied due to market volatility. Type display the order types. Status displays the current condition of your order. Time shows you when you placed the order.
This board shows your the latest trades including the long and short order. Green order displays the long(buy) position and vice versa.
You can check out what kind of Bitmex product you are using. If you see a perpetual contract, it is likely to be your best option. If you take a contract which is timely based, it will expire at some time and close your position automatically at the point of time, where the instrument has been closed and replaced. Perpetual contracts will never expire even if your position is one year old.
This board shows you wallet balance which is the amount of BTC you have, unrealised PNL, margin balance is the total amount of your wallet balance and unrealised pnl. Position margin is the amount of your position. Order margin is the amount of your open order. Available balance is the remaining after deducting all your open orders, positions.
Common Pitfalls on Bitmex
As advanced the interface of Bitmex is, there are some pitfalls new trades almost ALWAYS step in. We want to protect you on that, so better read it and consider it when playing with the Mex.
- Stop-loss did not work
If you wonder why your stop-loss did not work, it might be because you used a limit order instead of a market order. The price action, especially with XBT, is pretty fast sometimes. We recommend to use stop-loss only with Market orders, even the price is much higher in terms of fees – this is not the place to be cheap.
- Laddering in does not work due to liquidation price
So you get a trade signal with the instruction to ladder in at several price levels. You FOMO of not getting into the trade in time and buy at or near market price. From there a liquidation price exists and you cannot place orders for this instrument below the liquidation price anymore. It basically means you have to sit there and watch the price to go near liquidation to place the next ladder step, which can be very stressful. Hence we have to pull this up from the other side. We place our limit orders from the lowest to the highest/deepest price. If you set up your buy orders first, you will create an average price by each ladder step that has been reached, so the liquidation price becomes more irrelevant for the orders you placed. Conclusion: If you want to ladder into a trade, start with the lowest/highest order and work down/up from there in direction of the entry price.
- Instead of Stop-Loss, you find yourself in a new trade
This happens if you don’t use the dropdown for market/limit stops, as here the “REDUCE ONLY” checkbox is pre-checked. If it is not checked the system is able to buy/sell more than your current position. Example: You are long with XBT for 10,000 contracts. Accidentally you set your stop loss 10% below your entry price with 20,000 contracts. If “Reduce Only” is checked you still will just sell the 10k contracts you had. If it is unchecked, you will sell 20k contracts, which means you take the loss of the 10k contracts trade, but at the same time a new position of 10k contracts short is getting activated. This is especially annoying if you are stopped out by a huge wick and the price action returns to normal afterward – it basically could double your loss. Example: You are long from 6,5k with 10k contracts. You set your stop loss at 6.4k accidentally with 10k contracts. The stop loss is basically a short as you are selling your long contracts for the same amount of short contracts. If you type in 20k by accident or place another 10k order by being confused without reduce-only the mess is real: A huge wick appears down to 6,4k – sells your 10k long contracts against the shorts AND buys 10k shorts on top. This is the ultimate bad situation as you get stopped out by the wick AND have new short contracts, while it was just a wick and the price lifts up quickly again. UGH!
- A cross trade eats all your balance
The leverage option provides the whole range from Cross to 100x, if you trade on CROSS the leverage adjusts all the time and is not fixed. This means the trade can get fed by your account – even if this money is not in the trade yet. This option is super useful when trying to achieve certain things, but for the most traders, a cross trade will kill their account. If you check the bitmex calculator you can indeed calculate cross positions that cannot become liquidated, so it is a nice tool – but you have to use it smart and planned.
- Multiple orders due to “System overload”
If you do a clicky-clicky-clicky thing once the Bitmex system is overload, you might find many orders on your account Be careful and don’t Fomo. On fast price action, your whole account balance might find itself in one trade very quickly. System Overload = Take a step back until it settles.
- Bitmex Maintenance and Ending Contracts
If a Bitmex Maintenance is announced, be sure to get out of your positions before. Even if it is an isolated trade, it has been reported that Bitmex can take funds from your actually secured funds if the stop loss is exceeded while the maintenance. Also if a futures contract is not perpetual and therefore has a date where it gets replaced with a new one, be careful! Your position will be auto-closed once the date has hit.
- Price are in Bitcoin
You can lose track about your money pretty fast as everything is calculated in Bitcoin. Check our post about Bitmex Calculators to get aware of it.
- The Psyche
Bitmex can not only rekt your account but also your Psyche. Check our Bitmex Test to evaluate yourself and our Smart Memo Method to prepare your mind for trading.
Bitmex is extremely risky for new traders. Therefore, it is recommended to learn reading charts first before starting trading and always remember to set your leverage to 1x. On a side note, Bitmex has a testnet. You can get free testnet Bitcoin using these two websites:
