Thread: Questions on MT4 Error 130 [Invalid Stops]

Hi,

The purpose of this thread is to get answers to questions I have regarding MT4 error 130 [Invalid Stops] when I place either a OP_SELL or OP_BUY that has a Stop Loss & Take Profit specified on the OrderSend(). I am not looking on how to solve this problem. I have read enough posts to know that it is recommend to enter the OP_BUY/OP_SELL with no SL & TP. Then enter a OrderModify() with the SL & TP which will be picked up on the next tick.

Rather, the purpose of this thread is to delve deeper, to understand why brokers impose this restriction. I want for this post to be instructive, rather than just providing a way out from the problem. I would like to develop an understanding as to the rationale on why I have to submit two orders to perform one operation, the buying or selling an underlying instrument.

I hope someone with information on this topic will provide insightful information as to why this is the case. I do believe that appropriate answers on this topic will help those who have had to deal with this particular problem.

THANX(MKD).

MarketInfo will tell you minimum distance allowed to put stop and takes profit that your broker allow.

MarketInfo - MQL4 Documentation
use MODE_STOPLEVEL parameter

Perhaps there is a prohibition on enter the SL and TP levels at the opening of a order.
