You do not carefully read documentation. Please study it carefully. StaticVarAdd is not supposed to be run on first scanned symbol only ( Status( "stocknum" ) == 0).

/// Set symbol list in Analysis Filter - Include
/// And enable pad&align
/// Set Periodicity in analysis General settings
/// Create composite ARRAY via SCAN

list_name = CategoryGetName(categoryGroup, 5);
symbol_name = "~AboveMA_"+list_name;
cnt = "~cnt_"+list_name;
if ( Status( "action" ) == actionScan ) {
    /// @link https://www.amibroker.com/guide/afl/staticvaradd.html
    if( Status( "stocknum" ) == 0 ) {
        // remove any earier composite values
        StaticVarRemove(symbol_name);
        StaticVarRemove(cnt);
    }
    StaticVarAdd(symbol_name, C >= MA(C, 200), True, persist = False);
    StaticVarAdd(cnt, 1, True, persist);
    Buy = 0;
}

pcnt_aboveMA = Nz(StaticVarGet(symbol_name) / StaticVarGet(cnt))*100;
Plot(pcnt_aboveMA, "Percentage > 200 day ma", colorBlueGrey, styleThick);
