Supertrend and MACD alerts: know when the trend turns

The Supertrend trails a line behind the price and flips when the trend turns. The MACD shows whether a trend gains or loses momentum. Bellchain reports both via Telegram, with ▲ for up and ▼ for down.

How it works

Two indicators for trend turns

The Supertrend trails a line behind the price at the distance of its usual swings, by default from 10 candles times a factor of 3: below the price in an uptrend, above it in a downtrend. When a candle closes on its other side, the trend turns and the template reports the new direction. A larger factor gives rarer, clearer turns.

The MACD is the gap between the EMA 12 and the EMA 26, its signal line an EMA 9 of it. When the MACD crosses above the signal line while it is still below zero, a downswing turns; the template reports that and, mirrored, the turn down above zero.

  • Supertrend with 10 candles and factor 3 by default.
  • MACD with 12, 26 and 9 by default.
  • Both from Pro, testing in the replay without an account.

FAQ

Questions and answers

Which settings does the Supertrend use?

10 candles and a factor of 3 by default, as on the common charting platforms. A factor of 4 gives rarer, clearer turns; 4-hour candles show the bigger trend.

Why doesn’t the MACD template report every cross?

It reports crosses upwards below zero and downwards above zero, that is turns against the swing so far. Without that condition the chain reports every cross, much more often.

Can I combine Supertrend and MACD?

Yes. With AND the chain only fires, say, when the Supertrend points up and the MACD is above its signal line. The replay shows how often that would have happened.

Which plan do I need?

Supertrend and MACD come with Pro, which you can try free for 7 days. You can test both templates in the replay without an account.
