how it works
A python script is given access to user's exchange account and listens to websocket stream of live trades in the selected market, automatically creating and cancelling limit buy and sell orders.
It works in futures and spot markets. If exchange allows it, hedge mode is used to allow simultaneous long and short positions.
In spot markets bot mimicks futures behavior, allowing only long positions with max 1x leverage.
The bot bases its decisions on account's positions, open orders and balance, and multiple EMAs of different spans.
The EMAs are used to smoothe initial entries and stop loss orders.
Bot's live behavior is deterministic and may be simulated on historical price data, using the included backtester.
Its behavior is changed by adjusting the configuration to suit a particular market and user's preference.
Configuration's parameters may be optimized to a given period of historical data by backtesting up to thousands of candidates, converging upon the config whose backtest result best satisfy specified criteria.
Passivbot may be described as a market making DCA scalping grid trader.
-
Market maker: passivbot is a pure maker. It never takes orders, only makes them.
-
DCA: Dollar Cost Averaging. It will typically make up to several reentries after an initial entry, in an attempt to acheive better average entry price, similar to a Martingale betting system.
-
Scalping: It will typically close positions at small markups, in the range of 0.1-2.0%
-
Grid trading: Its reentries may be calculated in advance and put on the books, thus making a grid of orders.
There are price fluctuations in most markets, and the price noise may be "harvested". Ideally passivbot functions like a wind turbine or solar panel, passively gathering energy (money) from the environment (market).
For version specific information about configuring or using your version of the bot, refer to your version's documentation using the version popup at the bottom of the website.
In futures markets bot uses cross mode, so entire wallet is used as margin to any position. This means that one bad position may potentially liquidate entire wallet.
The bot does not use leverage in its internal logic, rather position-cost-to-balance-ratio called wallet_exposure, which is position size in terms of margin token divided by unleveraged wallet balance.
For example, 10% of available leveraged balance in a position at cross 20x leverage is equivalent to wallet_exposure==2.0, or 100% of available leveraged balance in a position at cross 2x leverage.
Upon startup bot will automatically set leverage to a high enough value to prevent insufficient margin errors. Other than that, leverage is irrelevant.
wallet_exposure == 1.0 means 100% of unleveraged balance is in a position.
wallet_exposure == 2.0 means 200% of unleveraged balance is in a position.
wallet_exposure == 0.15 means 15% of unleveraged balance is in a position.
Bot will not allow a position's wallet_exposure to grow higher than wallet_exposure_limit. When a position's wallet_exposure crosses wallet_exposure_limit, bot reduces position down to the specified wallet_exposure_limit.
The part of the position lower than or equal to wallet_exposure_limit is closed normally with a given markup percentage, while the part of the position exceeding wallet_exposure_limit is closed at the EMA bands (more on this elsewhere) at a potential loss.
You can prevent a position exceeding, say, 10% of unleveraged balance by making sure that wallet_exposure_limit + wallet_exposure_stop_loss parameters do not exceed 0.1 (==10%). If the price of the symbol would drop to 0, you'd lose a maximum of 10% of your wallet.
It is possible to run multiple pairs on the same account.
For example, if wallet_exposure_limit + wallet_exposure_stop_loss were set such that their sum was 0.05 on 10 bots, all of them combined will not expose
more than 50% of the account's unleveraged balance.
Another option available is to use the configuration parameter cross_wallet_pct to limit the amount of the wallet that is available
in absolute terms.
