Every additional backtest run increases the chance of finding good results by luck. The Deflated Sharpe Ratio (DSR) corrects for exactly this: it measures whether your result is real — or the best noise from N trials. Pro+ feature.

Most traders writing their own backtests accidentally look into the future. The result: spectacular backtests, collapsing live performance. A look at the subtlest methodology mistake in systematic trading — from the common `shift(-N)` to the innocuous `.mean()` aggregation without rolling window — and why we manually check every Backtesting Arena strategy for bias before release.

A buy signal fires — but the unlock calendar says a large tranche of supply hits the market in nine days. Do you take the trade? Using Hyperliquid and the FDV debate as the case: what the FDV-to-market-cap ratio really means, what token unlocks empirically do to price — and the one point-in-time trap that quietly makes almost every retroactive test worthless.

41 days ago, the first backtest ran in the Arena. Today, we crossed **10,000**. Average pace: **248 backtests per day**, every day. We didn't see this coming — and the numbers say more about you than about us.

Tokenized commodities are a $5.3B market — almost entirely gold. But silver, oil, and copper on-chain are now growing fast. What that technically means — and why these tokens can't (yet) be backtested like a classic ETF.

MEXC lists 3,000 coins, Binance 'only' 400. We still deliberately use Binance data exclusively. The reason is simple: a backtest is only as good as its price history. Here's why data quality beats coin count.
