新来的，关于小账户的头寸规模问题

Welcome! Beyond a fixed percentage, I've found it super helpful to think about sizing in terms of a fixed dollar amount risk per trade that feels manageable, especially starting out. Then, adjust your share count based on the stop loss for that specific trade.

Beyond the 1%, it often comes down to understanding your average true range for stop placement. If your stop needs to be wide, your share count must drop significantly to maintain that risk. Have you looked into 'volatility-based' sizing?
