Edit MQL4 Expert Advisor with Enhancements and Optional Features

Corrections and Additions:

1. Exclusion of Initial Trades: We will implement logic to prevent the opening of erroneous initial trades caused by Bollinger Bands. The system will initiate trading only after a certain number of candles or a specified time period.

2. Slippage Configuration: We'll add the ability to define the maximum allowable deviation in pips between the requested and executed price for each trade.

3. Resumption in Case of a Crash: We'll implement an automatic recovery function in case of an Expert Advisor crash. Additionally, we'll record the EA's state in trade comments to facilitate easy resumption.

4. Magic Number: We'll add the "magic number" feature to distinguish the EA's trades from those of other EAs on the same account.

5. RSI (Relative Strength Index) Usage (optional): If desired, we'll integrate an RSI filter that allows the EA to open trades only when the market is in an overbought or oversold state. Furthermore, you can configure this option to open positions only when the price exits the Bollinger Bands by a specific deviation (e.g., 200 pips).

6. Other Optional Features: We'll provide the ability to configure additional parameters, including slippage, spread, maximum number of trades per currency pair, maximum trades on Fridays, equity-based stop percentage, start and end trading hours, news filter, central bank events filter, speeches and testimonies filter, high-impact events filter, and options to halt trading at Friday's close or Monday's opening.
