Zero your count when the trend changes. Increment the count when you open an order. Test your count before opening. What's the problem?

thanks for reply, i saw your reply before https://www.mql5.com/en/forum/141838

static bool signalCurr; bool signalPrev = signalCurr;
signalCurr = ... // Your open condition
if (signalCurr && !signalPrev) ... // Now open

but it is not working , maybe i configure it wrong?
