Data Fetch Command Summary


Symbol Loop & Data Fetch

for i = 0 to array.size(symbolList)-1
    sym = array.get(symbolList, i)
    [c, y] = request.security(sym, 'D', [close, close[1]])
    chg = na(y) ? na : (c - y) / y * 100
    if not na(chg)
        array.push(chgList, chg)      // store % change
        array.push(nameList, sym)     // store symbol name
        gainers += chg > 0 ? 1 : 0
        losers  += chg < 0 ? 1 : 0

Sorting Function (Bubble Sort, Descending by % Change)

f_sortDesc(_a, _b) =>
    len = array.size(_a)
    if len > 1
        for i = 0 to len - 2
            for j = i + 1 to len - 1
                if array.get(_a, j) > array.get(_a, i)
                    tempVal = array.get(_a, i)
                    tempSym = array.get(_b, i)
                    array.set(_a, i, array.get(_a, j))
                    array.set(_b, i, array.get(_b, j))
                    array.set(_a, j, tempVal)
                    array.set(_b, j, tempSym)
