The ThreeCommasStrategy is a trading strategy implemented in Python for backtesting purposes. It has a confirm_trade_entry method that is responsible for confirming whether a trade entry should be executed. Here is a short description of what the strategy does:
The method receives parameters such as the trading pair, order type, amount, rate, time in force, and current time.
It checks if the confirm_trade_entry method is already implemented in the superclass.
If it is, an error is raised because the 3commas strategy will not work.
The trading pair is split into the coin and currency components. The strategy interacts with the 3commas API by using the py3cw library and the API credentials stored in environment variables (P3CW_KEY, P3CW_SECRET). A request is made to the 3commas API to start a new deal (trade) for the specified bot and trading pair. The response from the API is logged. A pair lock is created using PairLocks.lock_pair to prevent further trading on the same pair for the next 5 minutes. Finally, the method returns False, indicating that the trade should not be recorded in the frequency trading database. Overall, this strategy integrates with the 3commas platform and executes a buy order for a specified trading pair. It also implements a pair lock to prevent repeated trading on the same pair within a short timeframe.
