1. Calculate Your Maximum Dollar Risk
Your plan is to risk a maximum of 5% of your $200 capital on this single trade.
- Max Risk: 10**
This means the most you are willing to lose on this trade is $10.
2. Calculate the Risk per Share
This is the distance between your entry price and your stop-loss price.
-
Entry Price: 714.70
-
Stop-Loss Price: 689.59
-
Risk per Share: 714.70 - 689.59 = $25.11
Each share you buy has a potential risk of $25.11.
3. Calculate Your Position Size (Number of Shares)
Now, we divide your maximum dollar risk by the risk per share to find out how many shares you can buy.
- Calculation: 25.11 (Risk per Share) = 0.398 shares
Conclusion:
With a $200 account and a 5% risk limit, you can buy approximately 0.40 shares of LLY with this specific trade setup.
Since you likely can’t buy a full share, this tells you one of two things:
-
Your trading capital ($200) is too small for a stock this expensive with such a wide stop-loss.
-
You would need a broker that allows you to trade fractional shares to take this trade.
It’s also worth noting that the Risk/Reward ratio for your plan is (754.80 - 714.70) / (714.70 - 689.59) = 40.10 / 25.11 = 1.6:1. This meets the “>1.5:1” criteria in your plan, so the trade structure itself is sound!
