tastytrade backtesting alternative for plain-English stock rules
tastytrade does have a real backtester, Lookback, and it is strong, but it is built to test options strategies inside an options-first broker. Agenttrading tests a plain-English stock or ETF rule on 20+ years of adjusted daily data and hands back an honest verdict.

The honest comparison
tastytrade earned its following among active options traders, and its Lookback tool is a real, capable backtester, not a gimmick. Lookback lets you simulate almost any options strategy across roughly 2,000 symbols with about 12 to 15 years of history, matching the delta of each leg, and it even offers a forward-testing view that projects probabilities to expiration. If your world is options income, that is a serious edge, and this page is not here to talk you out of it. The honest comparison is about scope, not absence. Lookback is designed around options structures: legs, deltas, expirations. It is the right tool for "how would this iron condor on SPY have done" and the wrong tool for "how did buying SPY above its 200-day moving average hold up over 20 years". Those are different questions, and the second one is what Agenttrading exists to answer. You type the thesis in plain English, it restates the rule so you can see exactly what will run, backtests it on 20+ years of split- and dividend-adjusted daily data with a 0.1% cost per trade assumed by default, explains the risks in words, and stamps a one-line verdict: HELD UP, MIXED, or UNDERPERFORMED, even when the idea loses to buy-and-hold. There is also the broker point. tastytrade is a broker, so the same login that tests a strategy can place the trade. Agenttrading is not a broker and executes nothing, by design. Keep tastytrade for options execution and Lookback for options research, vet a plain stock or ETF rule on Agenttrading from $19 per month, then place the trade wherever you already trade. It is educational analysis only, never advice, and the decision stays yours.

On the same bench
The plain-sentence workflow is laid out on backtesting software, and the trading strategy tester shows how a sentence becomes the rule card the test runs on. Because Lookback is options-first, options backtesting covers where the two overlap, and does tastytrade have backtesting walks through what Lookback does and does not cover.

QUESTIONS - ASKED AND ANSWERED
tastytrade alternatives: the common questions
Does tastytrade have backtesting?
Yes. tastytrade offers Lookback, a real backtesting tool on its web platform that simulates options strategies across roughly 2,000 symbols with about 12 to 15 years of history and delta-matched legs. It is strong for options research. The limit is scope: Lookback is built around options structures, not plain stock or ETF rules like "hold SPY above its 200-day moving average".
Can you backtest stocks on tastytrade?
Lookback is designed for options strategies, so it is not the tool for testing a simple stock rule as-is. If you want to know how a plain-English stock or ETF thesis held up over 20+ years of adjusted data, a bench like Agenttrading runs that exact rule and stamps an honest verdict, then you can place any resulting trade at tastytrade.
What is tastytrade Lookback?
Lookback is tastytrade's backtesting and simulation feature. It lets you build almost any options strategy, real or hypothetical, match the delta of each leg, and see how it would have performed across about 12 to 15 years of history on roughly 2,000 symbols, with a forward-testing view that projects outcomes to expiration. It is options-first by design.
tastytrade vs Agenttrading: what is the difference?
tastytrade is an options-first broker whose Lookback tool backtests options structures with legs and deltas. Agenttrading executes nothing; you type one plain-English stock or ETF thesis, it restates the rule, backtests it on 20+ years of adjusted data, prints every assumption, and stamps an honest verdict including UNDERPERFORMED. One tests options strategies, the other tests the exact sentence you wrote.
Is tastytrade Lookback free?
Lookback is available to tastytrade customers on the web platform, so you use it with a funded account. It is genuinely capable for options research. If your question is about a plain stock or ETF rule rather than an options structure, that is a different job, and a plain-English bench answers it from one sentence, then you trade at tastytrade.
