Because I don't feel good about the Martingale option as well 🙂 I told you, even I don't know what to expect from these options, as there is no other option to select from where to get information about the next lot size. I don't know, something is missing for me about these options at the moment and in general I don't like adding functionalities when I'm not sure about them at 110%. Because if I add something and it turn out to be a bad idea, in the future I will need to deal with eventual problems
MM options are not totally clear even in Buy now/Sell now. Some people wanted to calculate the next lot size out of currently running trades, which is not exactly how Martingale should work. But now this is how it works - first the running trades are checked and after that closed trades. If you know this... okay, but if you don't know about this, who knows. For some reason no one reported problems with this behaviour, but I can only imagine someone who is trying to understand what is going on sometimes.
Again, there is something that is not clear for me in these options even for Buy now/Sell now, and for pending orders things are even more complicated. Maybe I need to rething how things happen and add some more options for control, but there are like 40 input parameters currently for Buy now/Sell now and it's already ugly 🙂 I just don't like the idea of adding more parameters in blocks who already have 10s of parameters.
