Field notes
The replay uses historical candles from Binance's public data and lets users choose a pair, timeframe, and date. Paper orders include market, limit, and stop types, while sizing follows the risk set by the user. Reviews record trade outcomes and notes, and indicators only see bars already released. The site says sessions remain in the browser; it also cautions that fees and slippage are not modeled.
