How it works
Build the buy and sell rules, run them over years of past candles, and read exactly what would have happened. It all runs on your device, with no account and no broker.
The builder
Build strategies with rules, not code
Add indicators to the chart, then tap conditions together into if-then rules: EMA 12 crosses above EMA 26, RSI below 30, price above a line you drew by hand. Tag each rule as a long or short entry or exit, and the strategy trades the moment its conditions line up. You never write a line of code.
Indicators
Over 110 indicators, plus your own
Trend, momentum, volatility and volume indicators, plus candlestick patterns, each drawn on the chart or in its own pane. Any condition can read a higher timeframe than the one you trade, so you can filter on the 4h trend while you enter on the 15m. If the indicator you want isn't here, write a formula and build it.
Risk & orders
Full control over how it trades
Stop loss, trailing stop, a time-based ROI ladder, leverage with isolated or cross margin, fees and slippage: each is a card showing its current value, so you can read the whole risk setup in one place. Volatility-based stops, confirmation rules, partial exits and DCA are there when you need them and out of the way when you don't.
Backtest
Test it against real history
The engine steps through years of candles one bar at a time, and only ever sees bars that have already closed, so a strategy can never peek at the future. On each bar it checks your stop loss, then take profit, then the trailing stop, then the ROI ladder and your exits, charging fees and slippage on every fill.
Intrabar PlaybackPro
Replay every trade, tick by tick
Watch a finished run trade forward: candles build, entries and exits appear where they happened, and the equity curve moves as each trade closes. Stops and targets are tested against a simulated path inside each candle, about twelve steps per bar, so they can fire mid-bar the way they would on a live exchange.
The report
Know exactly how it performed
Six headline numbers at the top, then the full breakdown: profit factor, expectancy, Sharpe and Sortino, max drawdown, win and loss streaks, holding times, and a day-by-day view. Every exit is labelled with the reason it closed, so you can see which rules made money and which ones cut winners short.
A few more tools
Smaller things you reach for while building and reviewing a strategy.
Tune every indicator
Open any indicator to set its periods, price source and colours, then shift or scale a value straight inside a condition instead of adding a second indicator for it.
A price-action toolkit built in
Market structure, order blocks, fair value gaps, liquidity pools and Chandelier Exit: 24 price-action indicators that plot on the chart and drop into your rules like any other.
Forex, crypto and stocks
Each market is sized and charged the way its own accounts really work, instead of one generic model for all of them.
01
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.
02
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.
03
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.
SoStonks Pro
One purchase, not a subscription. It unlocks everything below at once, on every device signed in to the same Apple ID.

Advanced orders
Custom stake sizing, partial take profit, and DCA with safety orders.

Your work stays on your device
There is no backend server and no account. You create and store your strategies, backtests and settings yourself, on your own device, and sync them through your own iCloud if you want. 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.
