Hej
Ok I understand "We do not provide Spreadsheet formula writing help", but this function that I use it once was, so they allow me to my question: By what this new function has been replaced, where you can program something similar.
Manny Thanks

The existing function "MACD crossover system" which already comes pretty close to what I am looking for, only should this not based on sluggish MACD, but better at faster on Moving Average-Hull. Who could help me with programming support me. This would be a powerful feature that would be very interesting to other future-traders.
