    How to use Market Analyzer as a scanner - 2

    Hi there,

    I am writing a custom indicator to be used in Market Analyzer. But I can't get any data other than [0]. Here is an example code:

    if ( SMA(50)[0] > SMA(50)[20] )
    {
    Plot0.Set(1);
    } else {
    Plot0.Set(0);
    }

    In code above, SMA(50)[0] work fine, but SMA(50)[20] is causing the following error:
    "Error on calling 'OnBarUpdate' method for indicator 'TrendDetector' on bar 0: You are accessing an index with a value that is invalid since its out of range. I.E. accessing a series [barsAgo] with a value of 5 when there are only 4 bars on the chart."

    I added :

    if (CurrentBar < 50); return;

    at the beginning of the code, but then code exits right there and never processes the rest.

    What I need is very simple as the code implies: I want indicator to plot 1, if SMA(50) value of today is larger than SMA(50) value 20 days ago.

    This is on a daily stock data.

    Any help is appreciated.

    Nick.

    Hi 10percent,

    First, your CurrentBar check has an extra semi-colon, should read as...

    Code:
    if (CurrentBar < 20) return;
    Also, you will only need to check this on 20 bars, as above.

    Try this on a chart first, make sure you have plenty of bars on the chart loaded (more than 50).
