Frequently Asked Questions
Can I backtest options strategies?
Yes — and this is rare. Most backtesting platforms including TrendSpider do not support options. TradeReplay uses real historical options data to backtest stock-only, option-only, or combined stock + options strategies.
Does TradeReplay support penny stock gap-up strategies?
Yes. There's a dedicated Gap-Up Penny Stocks instrument with 1-minute intraday data. You can test strategies like shorting the first red candle after a gap-up, with realistic borrow fees and walk-forward validation.
What US stocks can I backtest?
US stocks in three modes: intraday (1-minute data), daily (data from 2015), and penny gap-up stocks (intraday, full universe of daily gappers). Add specific tickers or use the full penny gapper basket.
Do I need to know how to code?
No. Describe your strategy in plain English — the AI writes the code. Designed for traders with intuition, not programmers.
What is walk-forward testing?
Walk-forward testing trains your strategy on one period and tests it on a future period it never saw. This prevents overfitting — the main reason strategies look great in backtesting but fail live. Most platforms skip this step.
How is it different from TradingView?
TradeReplay is mobile-first, requires no coding, supports options backtesting, and has walk-forward testing. TradingView requires Pine Script, has no walk-forward testing, and doesn't support options backtesting.
How is it different from TrendSpider?
TrendSpider does not support options backtesting or walk-forward testing. TradeReplay does both, with no coding required, on your iPhone.
