Supertrend Gold Signals - indicator for MetaTrader 5

The Supertrend line on Gold (XAUUSD) or any symbol is built from the candle midpoint, (high + low) / 2, plus or minus the ATR multiplied by a factor. Each band only moves in favour of the trend, and the trend flips when a candle closes on the other side of the active band. In an uptrend the line is green and sits below price, in a downtrend it is red and sits above price.

The arrow is drawn only after the flip candle has closed, never on the candle still forming, so an arrow you see on a closed bar stays there. Alerts follow the same rule: one alert for each closed candle with a flip, by popup, push notification or sound.

The line on the forming candle moves with price and can change side before the close. A Supertrend flip follows the trend, so it comes late in a range and gives back part of the move. Test the period and the multiplier on your symbol and timeframe before you trade it.

Settings

• ATR period: bars used by the ATR. Default 10.
• ATR multiplier: distance of the bands from the candle midpoint, in ATR multiples. Default 3.0.
• Show arrows: on or off. Up arrow below the low of the flip candle for a buy, down arrow above the high for a sell.
• Arrow distance: gap between the candle and the arrow, in ATR multiples. Default 0.5.
• Popup alert (on by default), push notification and sound (both off by default), plus the sound file name. The message carries the symbol, the timeframe, the direction, the time of the closed candle and its close price.

What it needs

Any symbol, any timeframe. It draws two lines and two sets of arrows with standard indicator buffers and it never trades. Push notifications need your MetaQuotes ID set in the terminal options. Wrong inputs (ATR period below 1, multiplier of 0 or less) stop the indicator with a message in the log.

Make it yours

Run it on XAUUSD, XAGUSD, EURUSD, GBPUSD, US30 or NAS100 and compare M5, M15 and H1 with the same period and multiplier. A lower multiplier flips more often, a higher one stays longer in the trend. From an EA you can read it with iCustom: buffer 0 is the uptrend line, buffer 1 the downtrend line, buffer 2 the buy arrow and buffer 3 the sell arrow. The band and flip logic sits in one loop inside OnCalculate and the alert text in XP_Notify, both easy to lift into your own code. It is a good place to plug a session filter, a news filter, a higher timeframe trend check or support and resistance levels before you take the signal.
