I'm having some trouble setting up RSI with the minute resolution. Right now I use think or swim to trade manually and am getting into quant connect. I understand that the RSI values between the two won't be exactlyl matching, but when I check the values on think or swim vs the values my algorithm is spitting out, they seem very different.

Currently I have it set up to spit out RSI value when it is under 30. There are times when it lines up, but also times when it says the value is 23 when it is 60+ on think or swim.

I feel like I'm missing something because when I set the resolution to daily, all the data seems to line up correctly.

Any help would be greatly appreciated!
