What is T3?

The T3 moving average, from Tim Tillson, applies a generalised double EMA several times to produce a smooth line with little lag. vFactor sets how much of the lag correction is applied.

T3 formula

OutputCalculation
GDEMA × (1 + v) − EMA(EMA) × v
T3GD applied three times

How to read T3 in your code

Limitations: With high vFactor values it can overshoot price. Nothing on this page is financial advice.

Compare the last two closed T3 values

Use backtrack=1 to skip the candle still forming, and results=2 to compare the last two closed candles. Arrays run oldest first.

curl -G https://v2.taapi.io/indicator/t3 \
  -H "Authorization: Bearer YOUR_API_KEY" \
  --data-urlencode "exchange=binance" \
  --data-urlencode "symbol=BTCUSDT" \
  --data-urlencode "timeframe=1h" \
  --data-urlencode "results=2" \
  --data-urlencode "backtrack=1"

Get historical T3 values

Add results to return a series for backtesting or charting. The last element is the most recent candle.

curl -G https://v2.taapi.io/indicator/t3 \
  -H "Authorization: Bearer YOUR_API_KEY" \
  --data-urlencode "exchange=binance" \
  --data-urlencode "symbol=BTCUSDT" \
  --data-urlencode "timeframe=1h" \
  --data-urlencode "results=100"

Get T3 for multiple symbols

T3 API FAQ

What does the T3 API return?

It returns value, plus a timestamp for the request. Results are JSON.

Is the latest T3 value final?

No. The newest value belongs to the candle still forming and can change until it closes. Add backtrack=1 to read the last closed candle.

Which T3 settings can I change?

You can set period, vFactor. See the parameters table above for defaults.

Can I get T3 for US stocks?

Yes. Use exchange=stocks with a ticker such as AAPL. US stocks are included on the Pro plan and above.
