Hi, 

I was trying to create RSI 2 daily and RSI 2 weekly together in daily chart. RSI daily was easy to do I was wondering how do we create RSI 2 weekly please?

Thanks & Regards,

There isn't a way to plot a calendar based weekly RSI on a daily chart in TC2000.

About the closest you can do is to based the RSI on the rolling 5-trading day per bar weeks used in TC2000 v7.

If it is a plain RSI without Wilder's smoothing:

100 * ((C > C5) * (C5 - C0) + (C5 > C10) * (C10 - C5)) / (ABS(C - C5) + ABS(C5 - C10) + .00001)

If the RSI is Wilder's smoothed:

50 * (C - .50003052 * (C5 + .5 * (C10 + .5 * (C15 + .5 * (C20 + .5 * (C25 + .5 * (C30 + .5 * (C35 + .5 * (C40 + .5 * (C45 + .5 * (C50 + .5 * (C55 + .5 * (C60 + .5 * (C65 + .5 * C70)))))))))))))) / 2 / (.50003052 * (ABS(C - C5) + .5 * (ABS(C5 - C10) + .5 * (ABS(C10 - C15) + .5 * (ABS(C15 - C20) + .5 * (ABS(C20 - C25) + .5 * (ABS(C25 - C30) + .5 * (ABS(C30 - C35) + .5 * (ABS(C35 - C40) + .5 * (ABS(C40 - C45) + .5 * (ABS(C45 - C50) + .5 * (ABS(C50 - C55) + .5 * (ABS(C55 - C60) + .5 * (ABS(C60 - C65) + .5 * (ABS(C65 - C70)))))))))))))))) + 50
