|
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
|

## Quick start
|
|
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
|
import numpy as np
|
|
|
|
|
|
import wickra as ta
|
|
|
|
|
|
|
|
|
|
|
|
# Batch — TA-Lib-style usage
|
|
|
|
|
|
prices = np.linspace(100, 200, 1000)
|
|
|
|
|
|
rsi = ta.RSI(14).batch(prices) # NumPy array; NaN during warmup
|
|
|
|
|
|
|
|
|
|
|
|
# Streaming — feed ticks one at a time
|
|
|
|
|
|
rsi = ta.RSI(14)
|
|
|
|
|
|
for price in live_prices:
|
|
|
|
|
|
v = rsi.update(price) # O(1) per tick
|
|
|
|
|
|
if v is not None and v > 70:
|
|
|
|
|
|
...
|
|
|
|

## Why streaming-first matters
|
|
|
|
|
|
|
|
|
|
|
|
Classic TA libraries are batch-only: every live tick triggers a full
|
|
|
|
|
|
recomputation over the entire history. Wickra updates indicator state in
|
|
|
|
|
|
O(1) per tick. On a 5K-bar history the streaming RSI gap is ~17× over the
|
|
|
|
|
|
nearest peer with a streaming API and 100×+ over batch-only libraries.
