The Custom ROC allows you to set the length of the ROC. You can also set a reference value, e.g. the ROC of the SPX. An upward deviation can also be set. This allows you to recognize which stocks have a higher ROC than a benchmark index (e.g. SPX). If the ROC is higher than that of the benchmark index, a green bar is displayed.
The Custom ROC Screener is structured in such a way that it can be used by the share screener.
