I would like to develop an Expert Advisor (EA) that uses the Moving Average and Bollinger Bands indicators to trade synthetic boom and crash pairs on the MT5 platform.

The EA should automatically execute trades based on the following conditions:

For Boom Pairs:

Buy when the Moving Average crosses above the upper Bollinger Band, and the candle's closing price is below both indicators.
Place a trade with a predetermined lot size.
Automatically set the stop-loss (SL) and take-profit (TP) levels in a 1:3 ratio or based on a certain number of candles.
Each time these conditions are met, a trade should be opened.
For Crash Pairs:

Sell when the Moving Average crosses below the lower Bollinger Band, and the candle's closing price is above both indicators.
Place a trade with a predetermined lot size.
Automatically set the stop-loss (SL) and take-profit (TP) levels in a 1:3 ratio or based on a certain number of candles.
Each time these conditions are met, a trade should be opened.
The EA should work simultaneously on all crash and boom pairs once configured and be functional across all timeframes. It should also provide the source code for further customization."

pls find the video how the indicator works. just want to automate the trades . =  https://www.youtube.com/watch?v=HflzM-yVEP8&t=125s
