大家好，我一直在努力提高仓位调整的纪律性，严格遵守每笔交易的资金百分比。但有一个问题总是困扰我，那就是当我试图建仓时，却只得到部分成交。比如说，我计划建仓100单位，但初始入场时只成交了50单位。然后价格波动了一下，我又成交了25单位。你们是在每次部分成交后重新计算风险，还是无论实际成交多少，都将最初计划的100单位视为最大风险？在交易过程中即时调整感觉很混乱，但如果我没有完全建仓，又感觉没有充分利用分配的风险。有没有经验丰富的交易员能分享一下如何处理这个实际问题？
Partial fills can definitely complicate things. For me, I set my max risk for the total intended position size from the outset. If I only get a partial fill, my actual risk is lower than planned, but I don't adjust the stop-loss or add more until the initial target size is reached or the trade is invalidated. How do you factor in slippage with your calculations?
This is a great question. Personally, I pre-define my total exposure for the trade and let partial fills accumulate up to that point. I don't recalculate risk mid-trade on each partial fill, as that can lead to chasing. Instead, I determine my full risk at the outset for the desired full position size.
Partial fills can definitely complicate things, especially with strict sizing. For me, if I don't get the full fill I wanted initially, I usually just work with the size I have rather than chasing the rest, especially if the price has moved significantly. It keeps the risk clearer.
