First level signal – when all indicators change color(Main_Signal, Entry, PairStrength, Bars) No need to wait for signal bar close, enter immediately.
Second level signal – The same as first level signal, but one of the squares may have different color(no matter is it Pairs_Strength square or Entry Square).There should be also acceleration arrow. You should wait till bar close and then enter. But if there are more than one differently-colored square – not to enter
2.Re-enter signal: Entry, PairStrength and Bars should have one color . This signal could appear only after first level signal or second level signal, when Main_signal indicator does not changes direction.. At the screen below re-enter signal appears after correction.
