Dsl - rsi - indicateur pour MetaTrader 4

RSI is mainly used in combination with levels or with a sort of signal lines. Some prefer the levels some, on the other hand, "signal" line. We could dispute which one is the better, but it probably mainly depends on trading style.

Here is a version that, in some way, combines the two types.
Discontinued signal lines idea is simple: when RSI value is above central value (rsi being 50), then only the upper signal line is calculated, and the lower signal line value is "inherited". When the value of RSI is below central value then the lower signal line is calculated and the upper signal line is "inherited". That way we are getting a kind of combination of levels and signal lines without a need to change the value of the RSI itself. As it is obvious it has its better sides compared to both methods (especially avoiding some problems with "trends" when signal lines alone are used). In any case extensive testing is advised.
