How much smaller should my position be if I will not be able to watch it during the trading day?

How this is calculated

• A resting stop-loss order placed with your broker executes whether or not you are watching the trade, so this tool applies no monitoring-based reduction when you confirm one is on file.
• Without a hard stop-loss order, you are relying on watching the trade and closing it yourself if it moves against you. The less often you can check it, the more your realistic worst-case loss can drift from your planned risk, so this tool suggests trimming size instead.
• These reduction factors, a 25, 50, 75, or 90 percent cut, are a simple convention set by Trading Habits, not a formula derived from any specific market or instrument.
• This does not address overnight or weekend risk, which can affect a position even with a hard stop-loss order resting, see the Overnight Exposure Calculator for that separate factor.
• The most reliable fix for limited monitoring time is usually placing an actual stop-loss order with your broker, not just trading smaller.
