What is Side-by-Side White Lines?
Side-by-Side White Lines is a 3-candle Japanese candlestick pattern. A gap in the trend direction is followed by two white candles of similar size opening at about the same level. It is usually read as a continuation of the gap direction.
How to read Side-by-Side White Lines in your code
| Signal | Meaning | Condition |
|---|---|---|
| Bullish | Bullish variant completed on this candle | value > 0 |
| Bearish | Bearish variant completed on this candle | value < 0 |
| Not detected | No pattern on this candle | value equals 0 |
Limitations: Candlestick patterns describe what already happened and are more meaningful alongside trend and volume. On 24/7 crypto markets there are few real gaps between candles, so gap-based patterns occur less often than on stocks. Nothing on this page is financial advice.
Detect Side-by-Side White Lines with Python
Check the last closed candle by adding backtrack=1. A pattern on the candle still forming can disappear before it closes.
curl -G https://v2.taapi.io/indicator/gapsidesidewhite \ -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"

headers={'Authorization': 'Bearer YOUR_API_KEY'},
params={'exchange': 'binance', 'symbol': 'BTCUSDT', 'timeframe': '1h', 'results': 2, 'backtrack': 1},
)
data = resp.json()
signal = data['value'][-1]
if signal > 0:
print('Bullish pattern on the last closed candle')
elif signal < 0:
print('Bearish pattern on the last closed candle')
else:

}Side-by-Side White Lines API FAQ
What does the Side-by-Side White Lines API return?
It returns value, plus a timestamp for the request. Results are JSON.
What do the Side-by-Side White Lines values mean?
0 means no pattern. A non-zero value means it was detected and is positive when bullish and negative when bearish. TA-Lib patterns commonly return 100 or −100, and some return other values such as 80 or −80, so check the sign and not an exact number.
Can I get Side-by-Side White Lines for US stocks?
Yes. Use exchange=stocks with a ticker such as AAPL. US stocks are included on the Pro plan and above.
