I know how difficult it can be to calculate in a brief time just
how many shares of a stock you can take while staying within
your risk parameters so here is a "cheat sheet" to help simplify
things. The following risk control sheet is based on a 20k
account and is the MAXIMUM you should risk on any one position. Ideal risk for larger accounts is 0.25%/trade. When
you first begin to trade, it is ideal to only risk $20/trade until
you develop consistency.

2% Risk in a 20k account. Total risk per trade = $400
