- On Free, paper trades have their own limit of 200 a month, separate from the 10 live trades. The app shows what is left.
- The app always shows your current limits: the Backtest page shows your units and per-run limits, My Bots your bot and coin limits.
- An administrator can change the limits of a single account. When the app shows different numbers for your account, the app is right.
Billing
- Choose a plan under Settings → Subscription in the app, or open app.optalgo.com/subscription. Pay monthly or annually.
- Payments are handled by Stripe. Depending on where you live, sales tax may be added to the final price.
- Paid plans come with a 14-day money-back guarantee. You can cancel at any time, in one click, from your account.
- A sub-account shares the plan of its main account.
Backtest units
A backtest is charged by its run time:
- 1 unit = up to 10 seconds of run time, at least 1 unit per run. A run of 1 minute costs 6 units.
- An optimisation (a research run) is charged in the same way, on its total run time.
- When you start a run, OptAlgo estimates its cost and reserves it from your quota. When the run ends, the charge is set to the real run time.
- No charge: checking (validating) a strategy, reading results, charts and diagnostics, a refused run, and a run that fails on OptAlgo's side. Running the exact same spec again costs at most 1 unit.
- Free counts units per UTC calendar month. Plus and Pro count them per UTC day, and the count resets at 00:00 UTC.
- When the units are used up, new runs are refused until the reset. Nothing else stops: bots keep trading.
To spend fewer units: use fewer symbols, a shorter period or a coarser timeframe, and fewer optimisation trials. Use one walk-forward research run instead of many single runs.
A run that needs more than your plan's per-run limits (symbols, history, trials, time, memory) is refused before it starts, with the limit it hit and a fix. Each run is also stopped at your plan's time per run.
What changes when you change plan
- Upgrade: the new limits apply at once.
- Downgrade to Free: your API keys keep working for what Free allows (reads, backtests, paper bots). Their live trading permission is ignored until you upgrade again.
- Strategies run on OptAlgo above the new plan's limit, and live ones on Free, wind down: only exits are sent until their positions are closed.
- Multi-symbol bots reject new entries on Free. Open positions can still be closed.
