There is nothing complicated in MQL5. The main thing you should do: uproot the word “order” from your head, and use the new word “position” and “pending order” instead.
Position is: BUY and SELL.
A pending order is: Buy stop, Buy limit, Sell stop, Sell limit ...
An example based on ChartPriceOnDropped will
be later ...

As I promised - here is the code. Here (just in case) a verification of the success of the modification is introduced. This check increased the code, but in case of an error it will be possible to see.
