The Support and Resistance Indicator is unique in that is involves price action patterns rather than typical swing high and swing low points. In fact it does not include and swing high or swing low points in the code, although upon closer inspection it does appear to pick out the correct swing high/low areas for support/resistance. Load the Support and Resistance Indicator on your chart and backtest it for yourself. You will see how price respects the areas of support/resistance many time before the area is weakened and price is able to eat through. For the patient trader waiting for ideal entry, the Support and Resistance Model can provide highly accurate trade levels based on specific price action and volume patterns which inherently cause price to stop and hesitate at such levels once it returns to it.
