ポジションサイジングは、ストップロスを設定するだけにとどまりません。ストップロスに達した場合に、総口座リスクが事前に定義された割合（例：1〜2%）内に収まるように、売買する適切な単位数（株式、契約、ロット）を決定することです。例えば、$DEFIを72.3897で見ていて、分析でストップが71.91だと示唆されている場合、口座残高と許容リスク割合を知ることが、安全に保有できる単位数を計算し、単一の取引が資本に不均衡な影響を与えるのを防ぐために不可欠です。
While that's a good start, it's also crucial to consider the volatility of the asset itself, not just a fixed percentage. A 1% risk on a highly volatile stock is different from 1% on a stable blue-chip.
This is a great point, it's easy to get tunnel vision on the stop-loss itself and forget about the larger picture of how that stop-loss impacts your overall account. Do you find that a fixed percentage risk per trade works best, or do you adjust it based on the setup's conviction?
It's good to see someone else acknowledging that there's more to position sizing than just picking a random number and hoping for the best. My broker usually reminds me of that when my account balance gets a bit too close to zero.
This makes so much sense! I've been so focused on just where to place the stop, I hadn't really thought about how that stop placement directly impacts how many shares I should even buy in the first place. So it's basically working backward from your risk tolerance?
