Hi BarrowBoy

Just a question

Why do we have to use OrderTakeProfit() in OrderModify rather than just setting own declared normalized Take Profit value

OrderModify(OrderTicket(), OrderOpenPrice(), Bid - TSTP, OrderTakeProfit(), Red)

Have searching in the forum for any answer to this question without luck

  1. You don't. It's just convenient to use. Rather than remember all existing values, the above line of code is only modifying the SL and keeping the rest the same.
  2. The above line is bogus, it's missing expiration.
