PipCaesar 2013.03.01 13:33

I don't know If any body knows why the RSI mq5 file that's submitted by MetaQuotes: rsi.mq5 does NOT wanna calculate the RSI(3) of GBP/CHF ?!?! not in any time frame particularly for this currency pair.

If any body can help me here Please?!

here is the code (that's inside this mq5 file If u can't view it):

Hello everyone;

I'd appreciate it If someone can help me here to know If I like to create Two plots of two different RSI values {RSI(14) & RSI(3)} using ONLY the RSI code posted by MetaQuotes file: rsi.mq5 "source code is down here", is there a more optimized method than creating another 3 buffers, or I can use the same ExtPosBuffer & ExtNegBuffer created from the first RSI coded?

I know there is other codes written to plot multi RSIs, but I wanna use this code specifically.

Thanx everyone.

I think you have to create new indicator using iRSI
