There was a bug in TRO_Multi_Meter_BB_TREND. I fixed it.
I had another idea. I added a line showing if the Bollinger Bands are expanding or contracting, or neither.
FREE MT4 version TRO_MM_BB_TREND, TRO_Multi_Meter_BB_TREND, and BollingerBands_TRO_MODIFIED_VERSION including SOURCE CODE, attached.
PLEASE DO NOT POST MY CODE ON OTHER FORUMS.
