Usage tips

How to use this result

Use this before a trade, not after you feel excited about the setup.

Enter your account size, risk limit, entry, and stop. The result shows how many shares you can take, how much you can lose, and whether the exposure is too large for the account.

Common use cases

  • Pre-trade risk planning before placing an order.
  • Watchlist review when several setups compete for capital.
  • Position cap checks after changing stop distance or account risk.

How to use it well

  1. Enter account size, risk percent or dollar risk, entry price, and stop price.
  2. Review max loss, share count, position value, and account exposure.
  3. Adjust the stop or risk limit until the position fits your written rules.
  4. Continue to stop planning, risk/reward, or a ticker decision card.

Practical tips

  • Start with the maximum loss you can accept, then let size follow from that.
  • Use conservative stops when gaps, spreads, or thin liquidity are possible.
  • Copy the result into your journal before entering the trade.

Limitations to know

  • This is educational risk math, not financial advice or a buy/sell signal.
  • It does not include gaps, slippage, commissions, taxes, leverage rules, or broker constraints.

FAQ

Q: Does this give buy or sell signals?

A: No. It only helps with risk sizing based on values you enter. It is educational decision support, not investment advice.

Q: Can I use it for stocks, crypto, or futures?

A: The math is generic. For futures or leveraged products, adjust the contract value and tick risk yourself before relying on the number.
