Quickstart

Your first cross-strategy correlation in three calls, no key — all historical data is free. New here? Start with Start here (try-it + the evaluate-against-your-book recipe). Base URL: https://api.btcalpha.com.au.

:::note Factual data, not advice Every response is backtested / modelled historical data for professional & institutional use. Past performance is not indicative of future results — not advice, not a recommendation, not a forecast. :::

1 · Discover the strategies

curl https://api.btcalpha.com.au/v1/strategies

Every response is the canonical envelope — data, meta, links. Example response — shape only; the metric values (and dataset_version) refresh daily, so … marks a live number — run the call for current data:

{
  "data": [
    {
      "id": "helios",
      "name": "Helios",
      "tv_status": "provisional",
      "verification_state": "dual_verified",
      "base_risk_pct": 0.025,
      "headline": {
        "cagr_pct": "…",
        "max_drawdown_pct": "…",
        "sharpe_daily_annualized": "…",
        "profit_factor": "…",
        "trade_count": "…"
      }
    }
  ],
  "meta": { "basis": "backtested", "dataset_version": "…", "count": 14 },
  "links": { "self": "/v1/strategies", "summary": "/v1/summary", "dataset": "/v1/dataset" }
}

Notice — two confidence signals on every strategy: verification_state is our internal validation depth (here dual_verified — confirmed two independent ways in-house), and tv_status is the external TradingView cross-check (provisional until reconciled; all 14 are provisional today). Two complementary axes, not a contradiction → Verification & data confidence.

2 · Pull the correlation matrix

curl "https://api.btcalpha.com.au/v1/correlation?period=daily"

Pearson correlation of aligned daily returns — risk-invariant (unchanged by risk_pct).

Notice: pairs span from the most-correlated (e.g. atlas / hyperion, strongly positive) down to the least (e.g. helios / kronos, near zero or slightly negative) — that spread, from tightly-correlated to negatively-correlated, is the raw material for diversification. (Exact coefficients refresh daily — read them from the call.)

3 · The diversification snapshot

curl https://api.btcalpha.com.au/v1/summary

The summary returns the diversification snapshot — mean correlation, effective bets — and the equal-weight book performance. All free, no key. Example response — shape only; … marks a live number that refreshes daily, so run the call for current values:

{
  "data": {
    "strategy_count": 14,
    "coverage": { "from": "2018-08-14", "to": "…" },
    "mean_pairwise_correlation": "…",
    "diversification": {
      "most_correlated":  { "pair": ["atlas", "hyperion"], "correlation": "…" },
      "least_correlated": { "pair": ["helios", "kronos"],  "correlation": "…" },
      "effective_bets": "…"
    },
    "equal_weight_book": {
      "n_days": "…", "net_return_pct": "…", "cagr_pct": "…",
      "max_drawdown_pct": "…", "sharpe_daily_annualized": "…"
    }
  }
}

What to notice: the least-correlated pair — helios / kronos — is near zero or mildly negative: a genuinely independent, even hedging, return stream. Over ~8 years (2018 → today) the 14 strategies behave like only a handful of independent bets (effective_bets) at a low mean correlation — that's the diversification, free to verify against your own book. (Backtested / modelled, provisional — not advice. Exact figures refresh daily; read them from the call.)
