What is SuperTrend V5?

SuperTrend is one of the most widely used trend-following indicators in technical analysis. Version 5 of this AmiBroker AFL is a comprehensive upgrade that combines the classic ATR-based SuperTrend calculation with a full alert system and a real-time GFX graphical dashboard overlaid directly on the price chart.

Originally developed by Rajandran R of marketcalls.in, this version adds popup window alerts with de-duplication (so you don't get spammed with repeated alerts), sound file playback, and gradient GFX data panels that display the current signal state without leaving the chart.

This AFL is 100% free. No registration, no watermarks, no DLL dependencies. Pure AmiBroker formula code.

How SuperTrend Works

SuperTrend calculates two dynamic bands around price using the Average True Range (ATR):

▲
Upper Band (Resistance) = MA(High, Period) + Multiplier × ATR(Period)
▼
Lower Band (Support) = MA(Low, Period) − Multiplier × ATR(Period)

When price closes above the upper band → trend flips to Bullish → Buy signal generated.
When price closes below the lower band → trend flips to Bearish → Sell signal generated.

The trailing stop adjusts dynamically with every new ATR value, widening during volatile periods and tightening in calm conditions — allowing you to stay in trends longer while protecting profits.

// Popup alert with de-duplication
function PopupWindowEx(popupID, bodytext, captiontext, timeout, left, top)
{
    displayText = bodytext + captiontext;
    if(StaticVarGetText("prevPopup"+popupID) != displayText
       OR StaticVarGet("prevPopupTime"+popupID) < GetSecondNum())
    {
        StaticVarSetText("prevPopup"+popupID, displayText);
        StaticVarSet("prevPopupTime"+popupID, GetSecondNum() + timeout);
        PopupWindow(bodytext, captiontext + popupID, timeout, left, top);
        PlaySound("c:\\windows\\media\\ding.wav");
    }
}

// GFX gradient data panel
procedure DrawData(Text, x1, y1, x2, y2, colorFrom, colorTo)
{

    GfxDrawText(Text, x1, y1, x2, y2, 32|1|4|16);
}

Trading Tips & Best Practices

⚠️

SuperTrend performs best in trending markets. In sideways/range-bound conditions it can generate false signals. Always combine with a broader market view.

✅

Works Best When

Market is trending with clear directional bias. Use on Nifty Futures, BankNifty, MCX Gold and Crude for best results on 5-min charts.

❌

Avoid When

Market is in a tight range near major support/resistance. During news events, expiry days, or pre-market opening gaps that distort ATR.

💡

Pro Tip: For Nifty Options trading — use SuperTrend signal direction to select call or put, then use your strike selection based on premium and time to expiry. Combine with ORB AFL for confluence entries.
