How the indicator works#
The middle band is the simple average of the selected window of closing prices. The upper and lower bands add and subtract the selected multiple of the population standard deviation from that average.
The calculation needs a complete window of candles. An incomplete window does not produce a valid band value.
Settings#
| Field | Observed form fallback | Purpose |
|---|---|---|
| Band Period | 20 | Number of closes used for the band calculation |
| Standard Deviations | 2 | Multiplier controlling band width |
| Signal Mode | Breakout | Breakout, Mean Reversion, or Middle Cross |
| Timeframe | Account-dependent | Candle interval used by the signal |
These are form fallbacks, not parameter recommendations. Review your saved values.
Choose the signal mode#
Breakout and Mean Reversion represent different interpretations of movement around the bands. Middle Cross uses the middle-band relationship. Select the intended mode explicitly; changing the mode changes the signal logic.
When comparing against another chart, match the period, deviation multiplier, candle interval, and price history. A sample-standard-deviation calculation will not reproduce population-standard-deviation bands exactly.
Configure execution and exits#
Set the execution contract and size after the signal settings. Use the shared risk and schedule steps for targets, stops, and entry windows. Review the monitor's actual signal before attributing a missing order to the band calculation.
If values differ#
Check the candle timestamp, finalized versus developing candle, and available history. Capture those details with the settings for support.
