The RSIDropDNSTrader strategy is a trading strategy that uses various indicators to make buying and selling decisions in the financial markets. Here's a short description of what the strategy does:
The strategy, implemented as a class named RSIDropDNSTrader, extends the IStrategy class. It contains a method called populate_indicators, which takes a dataframe of financial data and additional metadata as input.
Inside the populate_indicators method, the strategy performs the following steps:
It retrieves the trading pair from the metadata and initializes a TradeManager and a notification dictionary for the pair if they don't exist already.
It selects a subset of the dataframe based on the maximum number of bars back.
If the "notify_buy" flag is set in the notification dictionary, it sends a notification indicating that the pair was bought. Similarly, if the "notify_stop_loss" or "notify_profit" flags are set, it sends notifications for stop loss and profit events, respectively. If the strategy is running in live or dry run mode, it appends the ongoing candle data to the dataframe. It calculates various indicators such as bull and bear engulf lines, and determines the buy and sell criteria based on these indicators, ongoing prices, and predefined thresholds. If the trade manager doesn't have an open trade and the buy criteria are met, it opens a new trade and sets the stop loss price. If the ongoing close price triggers the stop loss or profit conditions, or if the sell criteria based on the bear zone are met, it closes the trade. The method returns the updated dataframe with additional columns indicating the buy and sell criteria. The strategy also includes helper methods for calculating the bull and bear engulf lines, finding the closest bull and bear green and red lines, and determining if the ongoing high price is above the closest bear green line.
