All lessons of Codersguru (for MT4) attached (just in case someone wants to learn mql4 for coding).
By the way, Codersguru is the member of our forum (his profile link) and he is the author of the famous MQL4 trading courses which he provided online on TSD forum.

We always should rememeber the people who were the first.

I attached pdf files of those codes to the post.

You have only four choices: We're not going to code it for you (although it could happen if you are lucky or the problem is interesting.) We are willing to help you when you post your attempt (using SRC) and the nature of your problem.
  1. Up to you
  2. Opposite of buy condition?
  3. Up to you
  4. Up to you
    • You place the stop where it needs to be - where the reason for the trade is no longer valid. E.g. trading a support bounce the stop goes below the support.
    • Account Balance * percent/100 = RISK = OrderLots * (|OrderOpenPrice - OrderStopLoss| * DeltaPerLot + CommissionPerLot) (Note OOP-OSL includes the SPREAD, and DeltaPerLot is usually around $10/pip but it takes account of the exchange rates of the pair vs. your account currency.)
    • Do NOT use TickValue by itself - DeltaPerLot
    • You must normalize lots properly and check against min and max.
    • You must also check FreeMargin to avoid stop out
  6. Up to you, e.g. target based on previous prices, based on multiple of the SL, trailing SL.
