What is Linear Regression Intercept?

The intercept is where the fitted regression line starts: its value at the first candle of the window. Combined with the slope, it allows you to rebuild the whole line.

Linear Regression Intercept formula

Output	Calculation
Intercept	b in the best-fit line y = b + m × x

How to read Linear Regression Intercept in your code

Signal	Meaning	Condition
Line start	Fitted value at the oldest candle	`value`

Limitations: It has little meaning alone and is mostly useful alongside the slope. Nothing on this page is financial advice.

Compare the last two closed Linear Regression Intercept 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/linearreg_intercept \
  -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"

)
data = resp.json()
prev, last = data['value']
print('value', prev, '->', last)
print('rising' if last > prev else 'falling or flat')

Get historical Linear Regression Intercept values

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