Problems with Standard Deviation

marie123 · Fri, 26 Nov 2021 07:16:11 +0000

Hello guys, I want to count how many times the price closed above the SMA(20) + 3*STD (=Bollinger Bands with deviation 3 instead 2). The screener-results are completely wrong. I think the syntax isn’t correct. Can someone help me please? count=0 for i=0 to 30 do upperBand=average[20](close)[i]+STD[3][i] if close[i]>upperBand then count=count+1 endif next SCREENER [count>0](count)
