Hi TraderX0, I'm confused as to why you decided to use the same close timeseries for all the different timeframes? Is it so you use can use closer to realtime values for the higher time frames ? Thanks for the help.

But why are you calculating RSI manually? Just wondering...

rp_security(_symbol, _res, _src) =>
request.security(_symbol, _res, _src[barstate.isrealtime ? repainting ? 0 : 1 : 0], barmerge.gaps_off, barmerge.lookahead_on)

rsi = rp_security(syminfo.tickerid, tf, ta.rsi(src, length))
