replayTradeExplanation
Replay one bot trade older than the bot's candle window: a backtest of the strategy version the bot runs, on the trade's pair, over the days around its signal candle, that records the values its entry branch read. Costs what a backtest on the bot's runner costs. explainTrade cites the values once it completed.
