In this video, we are going to create an Expert Advisor for Order Cancels Order strategies so you can place two pending orders above and below the current price, and as soon as the price reaches one of your orders, the other one is canceled. So let's see how we can do that with MQL5.

In this video, we are going to develop an Expert Advisor that opens Buy Stop and Sell Stop order when there are no positions or orders open, and cancels all pending orders when there is at least one open position. To do this, we'll be using MQL5 language. To begin, click on the small icon or press F4 on your keyboard, which will open the Metaeditor window. Now let's discuss the source code. The first part of the code is quite straightforward. We include the trade Trade.mqh file using an include statement allowing us to access the trade functions of MQL5. We then create an instance of the CTrade class which we name Trade. We move into the Ontick function, which is called every time a new tick is received for the symbol on the chart on which the expert advisor runs. Here we calculate the account balance and equity using the Account Info Double function.
