Backtester limits

The built-in backtester at /backtest enforces these per-plan caps. The same contract is exposed structured at GET /backtest/limits with your API key, useful when generating configs programmatically.

Server safety caps apply on top of plan limits: 1m timeframe is capped at 2 years of history, 5m–4h at 5 years, and a single backtest request returns at most 3 million bars total.

How credits work

function

Credits charge per feature, by tier

Features have a fixed cost regardless of date range, timeframe or number of bars: LIGHT = 1 credit, MEDIUM = 2 credits, HEAVY = 5 credits. Requesting returns + historical_volatility (both LIGHT) in one call = 2 credits.

pages

Pagination charges per page

Each page of a paginated request costs credits independently. 10 pages of historical_volatility = 10 credits.

Response headers

Header	Description
X-Credits-Charged	Credits consumed by this specific request.
X-Next-Start	Pagination cursor. Present only when more pages are available.

Rate limits

Two limits apply per API key: a per-minute credit budget and a cap on concurrent backtests. Exceeding either returns 429 Too Many Requests.

Plan	Credits / minute	Concurrent backtests
Demo	30	1
Basic	120	2
Pro	600	4

sync

Recommended strategy

For paginated loops, add a small delay between requests (time.sleep(0.5) in Python). If you receive a 429, wait 1 second and retry.
