The Script is for use with the strategy of the 4 rules of Daven Icao. It is an RSI
(black) with two Emas, 3 (blue) and 10 (red). To buy the RSI
is expected to cross with the Emas in oversold zone, which is level 25; level 75 is an overbought area where we expect the RSI
to cross with the Emas. If you consider that this script can be used in another strategy, use it! You can modify the values of the RSI
and the Emas.
