## What is SoStonks?

Backtest a trading strategy on forex, crypto or stocks, without writing a line of 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. Once the rules are in place, Optimize can look for the parameter values that suit them best.

FOREX

Sized and charged the way an FX account is.

• Stops, targets and trailing stops measured in pips
• Micro, mini, standard or custom lots, or size each trade from a fixed percentage of the account
• Spread in pips, plus commission per lot
• Swap charged long and short at real 17:00 New York rollovers, including Wednesday's triple day
• Leverage with isolated or cross margin, and liquidation priced off the margin actually posted
• Entries restricted to the Asian, London or New York session when you want that

Pairs come from Yahoo Finance for intraday and from Stooq for decades of daily history.

CRYPTO

Spot or perpetuals, long and short, with funding charged every eight hours and the same leverage and liquidation model. Candles come 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.

OPTIMIZE

Optimize tries different values for the indicators your rules actually use, and for your stop loss and trailing stop if the strategy has them. Leverage and stake size can be added too. You pick the date range and how many combinations to test: 120, 300 or 600.

That range is split in three. The search runs on the first 60%, the strongest sets are re-run on the next 20%, which the search never saw, and the last 20% is kept for one final check that plays no part in the ranking.

Results are sorted by a balanced score, return, max drawdown, Sharpe, Sortino, Calmar and profit factor, with the top five for each and a full report on every one. Save the result you want as a new strategy and the original stays as it was.

On iOS 26 a run keeps going after you leave the app. On earlier versions it pauses and picks up where it stopped.

Free accounts get 3 Optimize runs a day, with the same indicators and settings a free backtest has.

BUILDING AND TESTING

• A rule builder for entries, exits and filters, with no scripting anywhere in it
• Over 110 indicators and candlestick patterns, and any condition can read a timeframe other than the one you trade
• A trade log that records why each position closed, with totals split by entry and exit tag
• Every saved backtest keeps the exact settings it ran with, and they are printed in the PDF report
• Drawing tools on the chart: trendlines, horizontal lines, freehand, text, measure and Fibonacci retracement
• A strategy library you can organise, duplicate, and share by QR code
• iCloud sync, so a strategy built on your iPhone opens on your iPad with its saved backtests. No account needed
• Import from Pine Script, with a list of anything that couldn't be translated
• PDF reports, and export to Pine Script v5 for TradingView or to Python

SOSTONKS PRO

A single purchase rather than a subscription.

• Unlimited Optimize runs, including on strategies that use Pro features.
• 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.
• The Price Action toolkit adds 24 indicators: market structure, order blocks, fair value gaps, liquidity pools and Chandelier Exit.
• Custom stake sizing, partial take profit, and DCA with safety orders.
• Ads are removed.

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.

## Version history (last 5 releases)

### 1.1.6 — 2026-09-28

- Added strategy optimization to help you find better parameter combinations.
- Improved chart layouts on iPad and iPhone.
- More chart space during playback.
- Fixed playback position syncing when entering or leaving fullscreen.
- Improved condition-rule alignment and responsive wrapping.
- General performance improvements and bug fixes.

### 1.1.5 — 2026-09-26

This version adds Optimize. Pick a strategy and a date range, and it tests up to 600 combinations of your indicator settings, stop loss and trailing stop, then re-runs the best ones on candles the search didn't use. You can save any result as a new strategy. Free accounts get 3 runs a day, Pro has no limit.
The Pine Script importer was rewritten. More scripts come across correctly, and anything it can't translate shows up under "Needs attention" so you know what to fix by hand.
Two new chart tools: freehand and text. You can edit and resize text after placing it.
Saved backtests now show the exact settings they ran with, and the PDF report includes them.
If a strategy uses premium/discount zones, those zones are now evaluated the same way the chart draws them. Its results may change, so re-run any saved backtests you rely on.

### 1.1.4 — 2026-09-16

Small fixes and improvements throughout the app.

### 1.1.3 — 2026-09-13

Playback got a solid upgrade in this release. You can now replay longer sessions, zoom the timeline, scrub to an exact time, and move through large datasets more smoothly.
Open trades also show their stop-loss and trailing-stop levels directly on the chart. We’ve also fixed accidental detail popups while zooming and reduced background resource usage.

### 1.1.2 — 2026-09-08

Your strategies and backtests show up the moment you open the app now, instead of sitting there while iCloud catches up.
You can save a Playback report as a PDF.
Playback scrubbing feels smoother, the backtest history opens faster, and the numbers behind your results are a little more accurate.
