Rewindex
Crypto strategy backtests for iPhone

Rewind the market.
Test your rules.

Rewindex replays a rule set on an asset's past daily prices and writes up what would have happened: each entry and exit, the equity curve, drawdowns and a month-by-month grid.

Rewindex mark

Lab

Pick an asset and a template — MA Cross, RSI Reversion, Breakout, Band Bounce or DCA — then tune lookbacks, stops, targets, position size, fees and slippage. The chart updates as you adjust.

Reports

Price with entry and exit markers, equity against holding, drawdown, monthly returns, statistics such as Sharpe and time in market, and a list of positions.

Seasons

See an asset's own calendar: each month since it was listed, the average and share of up months, and the average move by weekday.

Markets

Larger coins with daily price history, with 7-day lines, a candle chart you can zoom, key statistics and how each template fared over the past two years.

Runs & Compare

Tests you run are kept on your device. Reopen one, adjust it in the Lab, or line up two or three side by side.

Playbook

Plain explanations of each template, where it can struggle, how to read a report and how tests are run.
