Mastering Algorithmic Trading: Creating an Automated Bot

Chapter 1: Understanding Trade Execution
In the ever-evolving landscape of algorithmic trading, executing trades efficiently is crucial for any successful strategy. The Strategy abstract class serves as a foundation for crafting advanced trading algorithms, encapsulating the core principles of trade execution through its implemented methods. This exploration delves into the detailed mechanics of executing both long and short trades within the Strategy class, shedding light on the strategic and technical elements that drive effective trading operations.
Section 1.1: Initiating Long Trades
The _long method in the Strategy class plays a key role in executing long trades, which entail purchasing an asset with the expectation that its price will rise. This method carefully determines the trade size, factoring in the asset's leverage, the trader's risk tolerance, and the current equity, all while adhering to risk management guidelines.
def _long(self, price: float, risk: float) -> None:
trade_size = min(self._asset.max_leverage * self._equity, (self._asset.max_risk / risk) * self._equity)
coins = round(trade_size / price, self._asset.decimals)
self._position += coins
self._equity -= (1. + self.ec.taker_fees_USD_futures) * coins * price
Once the optimal trade size is calculated, the method updates the strategy's position and equity to reflect the newly established long position.
Section 1.2: Executing Short Trades
In contrast, the _short method facilitates the execution of short trades, allowing the strategy to profit when the asset's price declines. Similar to the _long method, it calculates the trade size while taking into account the strategy's risk parameters, subsequently adjusting the position and equity accordingly.
def _short(self, price: float, risk: float) -> None:
trade_size = min(self._asset.max_leverage * self._equity, (self._asset.max_risk / risk) * self._equity)
coins = round(trade_size / price, self._asset.decimals)
self._position -= coins
self._equity += (1. - self.ec.taker_fees_USD_futures) * coins * price
This method showcases the Strategy class's capability to adapt to changing market dynamics, enabling traders to take advantage of both bullish and bearish movements.
Chapter 2: Closing Trades
The Strategy class also features mechanisms for closing trades, ensuring that the strategy can secure profits and mitigate losses. The _close_long_trade and _close_short_trade methods are specifically designed to exit long and short positions by reversing the initial trade actions.
def _close_long_trade(self, price: float) -> None:
coins = self._position
cash = self._position * price
self._equity += (1. - self.ec.taker_fees_USD_futures) * cash
def _close_short_trade(self, price: float) -> None:
coins = self._position
cash = self._position * price
self._equity += (1. - self.ec.taker_fees_USD_futures) * cash
These methods ensure efficient exit strategies based on established criteria or risk management rules, highlighting the importance of flexibility and control in managing trades.
