Opening or closing based on latest open position
Hello everyone!
I am entirely new to trading, MQL5, or coding in general. Trying to learn something new during the lockdown days so please excuse my ignorance.
I am basically trying to code an EA that will open or close positions based on the profit of my most recent open position. I have found that I should probably use PositionGetDouble( POSITION_PROFIT ) but I am quite confused as to how I should arrange my cache to include only the most recent open position and adjust automatically as the EA opens and closes new positions.
I would really appreciate any and all help.
Thank you very much in advance!
Sample code.

The EA does not work with the trading history (it is assumed that the EA works all the time, the EA will not turn off, you will not switch the timeframe on the chart). How the adviser catches the moment of closing a position - it catches the closing of a position in OnTradeTransaction : waiting for the transaction TRADE_TRANSACTION_DEAL_ADD - adding a deal to history .
As soon as the deal "TRADE_TRANSACTION_DEAL_ADD - adding a deal to history" is caught, the adviser displays a comment on the chart. ATTENTION: the transaction is searched by the current symbol and BY THE PRESET Magic Number
