@mcarl42 You select different TF's on each option and this creates a loop that changes all connected blocks beneath to the other timeframes, a diffract one for every loop.
I guess you're talking about communicating mora than one MT4 platform. If so, you will need to master the infamous 'Terminal Variables' to do it. Not an easy thing to do, IMHO. Maybe a real programmer (not me) can help you.
@mcarl42 On x> / x< you might change the parameter for width, but I'm nit sure that this would be exactly what you are looking for. If you specify width of 5. the cross could have happened within the last 5 candles and it has not crossed down yet again. Maybe that help a bit!?!
