Check the WIN and LOSS results of signals based on support and resistance zones, using your trading history. This lets you measure whether a zone strategy really works on your data.
The rate and zone checker is useful to measure whether a support and resistance strategy really works on your data. It checks the WIN and LOSS results of each zone-based signal.
In practice, the checker comes after you already have zone-based signals. It shows, with your own data, which regions really produced WIN and which piled up LOSS. This feedback lets you refine the strategy: keep the zones that work, adjust the marginal ones and drop those that only brought losses, instead of trading all of them equally out of confidence in the method.
