Popov

Indicator was updated to v2.4.

Changes: Removed unused components representing Central MA of both bands.

Popov

MQL code updated. Fixed a typo in the logic rules that blocked indicator from trading.

Popov

Indicator works only on Close price. Other base prices were removed because of wrong set of "Use previous bar value".

footon

Indicator updated to v2.5
Changes: return of all available baseprices, fix of ATR calculation.
