Dear Friends,
I request the programming experts to convert the following MT4 script to Amibroker AFL.

SetIndexStyle(0, DRAW_LINE, STYLE_SOLID, 2);

return (0);
}

int counted_bars = IndicatorCounted();
if (counted_bars < 0) return (-1);
if (counted_bars > 0) counted_bars--;
int limit = Bars - counted_bars;

for (int shift = limit; shift >= 0; shift--)
{
thisCCI = iCCI(NULL, 0, CCI, PRICE_TYPICAL, shift);
lastCCI = iCCI(NULL, 0, CCI, PRICE_TYPICAL, shift + 1);

if (thisCCI >= 0 && lastCCI < 0) bufferUp[shift + 1] = bufferDn[shift + 1];
if (thisCCI <= 0 && lastCCI > 0) bufferDn[shift + 1] = bufferUp[shift + 1];

if (thisCCI >= 0)
{
bufferUp[shift] = Low[shift] - iATR(NULL, 0, ATR, shift);
if (bufferUp[shift] < bufferUp[shift + 1])
bufferUp[shift] = bufferUp[shift + 1];
}
else
{
if (thisCCI <= 0)
{
bufferDn[shift] = High[shift] + iATR(NULL, 0, ATR, shift);
if (bufferDn[shift] > bufferDn[shift + 1])
bufferDn[shift] = bufferDn[shift + 1];
}
