I have added 5 Min, 15 Min, 30 Min, 1 Hr and 1 Day time frame in one Chart. You can select and combine whichever the TF you want.
Default values considered - Period - 20 and Std.Dev is 2
You can on/off the indicator based on the requirement.
- BUY - When price comes near to the Bottom level (look for candle confirmation is plus). If multiple travels together then is Strong Support. (Exit if Price Breaks down the BB)
- SELL - When price reaches the Upper level (look for candle confirmation is plus). If multiple travels together then is Strong Support. (Exit if Price Breaks Up the BB)
When the Gap between Upper and Lower Band is narrow then we can expect a trending movement soon.
