    If I am using the default 14 period setting for RSI...why would two different programs...in this case Quotetracker using an IB feed and Qcharts have such different values? Not only that but the Bollinger Bands are also a little off?
     
  2. This might be the best thing that has happened to you.

    You are learning that indicators are only as good as the data.

    Except in this case the data appears to be identical. The sources are different...but I'm looking at intraday 5 minute charts and over the standard 14 period RSI they appear to be identical..and yet the RSI are different.
     
  4. Are both your charts set-up in the exact SAME type of scale?

    ( ie. logarithmic vs linear ).

    The Charts in QCharts are Logarithmic...I don't see the option in Quotetracker. I was thinking that too...I'll have to look into it. Thanks for the reply.

    It turns out that there are 2 ways to calculate RSI and Quotetracker calculates it differently than QCharts. j_medved
    suggested that I double the period in Quotetracker and that did it. So thanks j_medved!
