Simulate a crypto bot strategy: an honest backtest
Before you risk a cent, you can see how a strategy would have behaved. Theta's backtest simulator runs the strategy over real candles going back to 2017 — and shows the actual result, positive or negative.
Most tools only show the pretty scenario. Theta does the opposite: it shows the red too. In the same run, BTC closed +83.8% and ETH +10.1%, and the worst drawdown along the way was −50.9% and −63.9%. You see all four numbers before turning the bot on live.
Why trust it
The API key reads and trades, and cannot withdraw. And the refusal errs on the safe side: if the exchange answers in a way that does not let the permissions be confirmed, the connection does not complete at all. Your funds never leave your exchange account.
Not a philosophy, an engine lock: on its own it requires 0.35% above average cost, which covers the round trip of the fee plus room (the exact fee varies by exchange). If price drops, the bot holds and reopens later. The lock is on what the bot does by itself, not on you: telling it to sell now is still your call.
Simulate with a virtual balance, no time limit, before risking a single real cent. The simulator runs against real candles from the exchange itself, so it is what reproduces any number we publish.
On managed bots, the Pilot's Plan adjusts how many coins and how much per coin from the money available at the exchange — climbing a public ladder as the capital grows. If it cannot read the exchange balance, it does not plan the step: it would rather stop than guess a number.
What the simulator does
It applies the strategy over the real price history and reports the cumulative return. The simulator lives inside the product — this page explains it; to run it, you head into Theta. There's also a live test mode with a virtual balance: in a recent sample it closed 181 cycles, with a result of +83.56 USDT, a rising curve, and CSV export. Short sample — it doesn't project the future.
Honesty is showing the red too
Most tools only show the pretty scenario. Theta does the opposite: in the same run, BTC closed +83.8% and ETH +10.1%. Same strategy, same period, and an eightfold gap between them: we put both side by side, each with its worst drawdown. Backtests inform, they don't predict.
| BTC · return | +83.8% |
| BTC · worst drawdown | −50.9% |
| ETH · return | +10.1% |
| ETH · worst drawdown | −63.9% |
Run on the product's own simulator on Aug 31, 2026 with exactly this configuration, so you can redo it and check. Same strategy, same period, and an eightfold gap between the two coins. Plain holding would have returned +58.4%, with a −76.6% drawdown along the way. Backtests inform, they don't predict.
Backtests inform, they don't predict
A good historical result is not a promise of the future. Markets change, and a preset that shone over past years can fail ahead. The simulator is there to calibrate expectations — not to promise a return.
