Input Parameters: The EA should feature an input mask with 12 fields to input various dates, allowing the EA to trade only on those specified dates. Also, as the time zone changes twice a year in the USA, it must be possible to enter the times manually to adjust accordingly.
Trade Direction: Long Only
Lot Size/Risk management: There should be the option to manually adjust the risk management percentage value, with a default setting of 3% according to the account size.
Trading Instrument: The EA should trade the US500.
Trade Visualization: Trades executed by the EA should be visually represented on the chart.
Backtesting Functionality: The EA should allow for backtesting to assess its performance. If not inherently available in MQL5, the programmer should integrate this feature.
Stop-Loss: Utilize the ATR indicator to determine and set the stop-loss for each trade. The stop-loss should be set at 3 times the 20-day average of daily ranges. - (ATR20) Daily * 3
