What is Directional Indicator?

This endpoint returns both directional indicators in one response: +DI measures upward movement and −DI measures downward movement, each as a share of the average true range.

Directional Indicator formula

Output	Calculation
+DI	Smoothed +DM ÷ smoothed true range × 100
−DI	Smoothed −DM ÷ smoothed true range × 100

How to read Directional Indicator in your code

Signal	Meaning	Condition
Bullish bias	Upward movement dominates	`plus_di` above `minus_di`
Bearish bias	Downward movement dominates	`minus_di` above `plus_di`
Crossover	Direction flipped	`plus_di` crosses `minus_di`

Limitations: DI crossovers whipsaw in ranges. Check ADX to see whether a trend exists at all. Nothing on this page is financial advice.

Compare the last two closed Directional Indicator values

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

  --data-urlencode "exchange=binance" \
  --data-urlencode "symbol=BTCUSDT" \

    headers={'Authorization': 'Bearer YOUR_API_KEY'},
    params={'exchange': 'binance', 'symbol': 'BTCUSDT', 'timeframe': '1h', 'results': 2, 'backtrack': 1},
)
data = resp.json()
prev, last = data['plus_di']
print('plus_di', prev, '->', last)
print('rising' if last > prev else 'falling or flat')
