Position Size, Cash Rules, and Targets
You can size a position from a risk limit and confirm the cash is genuinely available.
Lesson objective
Be able to size a position from your limits rather than your enthusiasm, and explain why a small target cannot rescue an unmanaged loss.
Preview
Buying power is not the same as settled cash. This lesson turns a risk limit into a share count, explains how cash-account settlement limits how often you can act, and covers how Good Faith Violations happen in the first place.

Risk reminder
Never size up to 'make the trade worth it.' If the position needs to be larger to feel meaningful, the setup is not the problem — the expectation is.
