Backtest a trading strategy without writing code.
You build the buy and sell rules by tapping them together, run them over years of past candles, and read back what would have happened: win rate, drawdown, profit factor, and every trade in a list.
Requires iOS or iPadOS 17. Free with an optional one-time Pro purchase.
Forex, crypto and stocks
Each market is sized and charged the way its own accounts work, not with one generic model.
Forex
Stops and targets in pips, micro to standard lots or a fixed risk percentage, spread and commission, swap at real 17:00 New York rollovers, leverage with isolated or cross margin, and an optional Asian, London or New York session filter.
Crypto
Spot or perpetuals, long and short, with funding charged every eight hours and the same leverage and liquidation model. Candles from Binance, Bybit or OKX.
Stocks
Long or short over daily and intraday history from Yahoo Finance, with commission and slippage applied. Any market can also be loaded from your own CSV.
Candles are pulled straight from public market endpoints: Binance, Bybit and OKX for crypto, Yahoo Finance for stocks, indices, ETFs and FX, and Stooq as a fallback for decades of daily history.
Build it, then test it
A rule builder with no scripting anywhere in it, and an engine that steps through history one candle at a time.
Rule builder
Assemble entries, exits and filters by tapping conditions together. No code, ever.
Over 110 indicators
Indicators and candlestick patterns, and any condition can read a timeframe other than the one you trade.
A trade log that explains itself
Every position records why it closed, with totals split by entry and exit tag.
iCloud sync
A strategy built on your iPhone opens on your iPad with its saved backtests. No account needed.
PDF reports and code export
Save a report as a PDF, or export the strategy to Pine Script v5 for TradingView or to Python.
A strategy library
Organise, duplicate, and share strategies by QR code, with drawing tools on the backtest chart.
SoStonks Pro
One purchase, not a subscription. It unlocks everything below at once, on every device signed into the same Apple ID.
Intrabar Playback
Replays a finished run forward through the data the way a live bot would meet it, stepping inside each bar so stops and targets fire on real intrabar price instead of on the close.
Price Action toolkit
Adds 24 indicators: market structure, order blocks, fair value gaps, liquidity pools and Chandelier Exit.
Advanced orders
Custom stake sizing, partial take profit, and DCA with safety orders.
No ads
Ads are removed everywhere in the app.
Your work stays on your device
There is no backend server and no account. Your strategies, backtests and settings are created and stored by you, on your own device, and optionally synced through your own iCloud. SoStonks never receives a copy.
SoStonks never places a trade and never connects to a broker. Everything is computed on your device from public historical prices. This is not financial advice, and past performance does not guarantee future results.
