In the populate_buy_trend method, the strategy defines the conditions for entering a buy trade.
The conditions include checking if the close price is below a moving average (ma_buy), if the Elliott Wave Oscillator (EWO) is above a certain threshold (ewo_high), if the RSI is below a certain value (rsi_buy), and if the volume is greater than zero.
The strategy likely has additional methods and parameters that are not shown in the provided code snippet.
