If you would like to visually see the support/resistances that the chart is plotting, you can toggle them on with the ‘Plot Support and Resistance’ option at the bottom of the indicator’s settings.
- Support/resistance needs to be the lowest low/highest high for this many bars before it.
- Support/resistance needs to be the lowest low/highest high for this many bars after it.
Assuming left bars lookback is 15 and right bars lookback is 15:
- is plotted when the low of a candle is lower than the low of the last 15 bars before it, and remains the lowest low for the next 15 bars after. So a support is plotted 15 bars after the low actually happened.
- is plotted when the high of a candle is higher than the high of the last 15 bars before it, and remains the highest high for the next 15 bars after. So a resistance is plotted 15 bars after the high actually happened.
