EVEN THOUGH ITS FEW MONTHES I AM STUDDYING FXDREEMA BUT I STILL NEED YOUR HELP ABOU THIS DIFFICULT QUESTION , SURE OF YOUR HELP ..
SIMPLY : HOW TO SAVE IN A VARIABLE THE INDICATOR VALUE AT THE MOMENT OF OPENING EACH NEW TRADE???
I want to store the value of the volume indicator at the moment of opening the initial trade in a variable, and then compare the indicator's value on each subsequent tick with its value at the last previous trade. Above, is the Expert Advisor I created, the problem is that it doesn't link the indicator's value to the trade at the moment of opening. As you can see from the attached screenshot, the indicator's value keep changıng for both the open trade and its current value with each tick. In reality, the indicators value for the open trade should be fixed (must change only when new trade is opened ) , and the value for each tick should change. However, what's happening with the attached Expert Advisor is that all three values are changing together...!!"
