Custom ThinkOrSwim Position Size Calculator Study

Custom Thinkorswim Position Size Calculator – Trade With Real Risk Control

If you’re still manually calculating your position size, you’re leaving money on the table — or risking way more than you realize. This custom Thinkorswim study does it all for you, automatically:

• Entry = current market price
• Stop = daily low
• Risk = your chosen % of account
• Shares = calculated instantly
• Position value shown live

No spreadsheets. No overthinking.
Just clean, repeatable execution.

Whether you risk 0.5%, 1%, or 2% per trade, this calculator gives you the exact share size you need for consistent risk management — the same approach elite swing traders use to compound aggressively without blowing up. The only thing you need to edit yourself in the code, is your account value.

If you want to scale your account responsibly and trade with actual discipline, this tool needs to be in your Thinkorswim setup.
