# Author: @ntsd (Jirawat Boonkumnerd)
# Github: https://github.com/ntsd
# V2 Update: Add periods for each timeframe
# V3 Update: Add operators
# V6 Update: Optimise by categories
# V7 Update: Optimise by using int parameter
# V8 Update: sell trend condition use from buy condition
# V8.1 Update: Remove second timeframe and second indicator to use same as first
# V9 Update: use all timeframe but optimise periods
