Resistance and Support Afl amibroker

After months of hardwork, I was able to find this  code, You can use it to find the Resistance and Support of any timeframe in Ambroker. This can be used in weekly timeframes to pick weekly stocks for short term trading.  These levels are also called as the demand and supply zones. I will update in another post about how to pick stocks for weekly timeframes using this amibroker formula.

thanks for reading : )

thanks to original creator of this afl : )
