Portfolio replay

What would the rules have done with your trades?

Upload your own holdings and this replays every position under ZycaAlgo's exit rules — a 15% stop, a trailing stop 10% below the high once a position is up 15%, and a 90-day exit if it goes nowhere — then shows the result beside what actually happened.

It reports what the discipline did, in whichever direction. Sometimes rules rescue a position that ran away from you. Sometimes they cut a winner short. Both are worth seeing on your own money rather than on a backtest.

Your file is read in your browser and never uploaded — only the ticker symbols are sent, to fetch public price history. Nothing about your positions, sizes or prices leaves this page.

Works with a Yahoo Finance portfolio export as-is. Any CSV with a symbol, purchase price, quantity and trade date will do. Rows without a purchase recorded are treated as watchlist entries and skipped.

This is a counterfactual on daily bars, not a record of trades that happened. A stop is assumed to fill at the stop price the moment the day's low crosses it; a real fill would slip, and a gap down would fill worse. It also can't know what you would have done with the cash a rule freed up, which for an early exit is often the whole question. Read it as a measure of what the discipline does to a position, not as a forecast of what you would have ended up with.
