Private browser-only worksheet

A free risk-first pre-trade review template

Write the decision before the order ticket. This worksheet checks the minimum review fields and calculates a simplified whole-share ceiling without collecting a symbol, notes, account details, or the values you enter.

Direct answer

What should a pre-trade review template contain?

At minimum: the current source and time frame, observable setup, entry condition, thesis invalidation, maximum dollar-risk budget, whole-unit size, execution constraints, and the condition that means no trade. The calculator below answers only the arithmetic question. It cannot approve the trade, evaluate suitability, guarantee an execution price, or cap realized loss.

Worksheet status

Inputs incomplete

Add entry, invalidation, and dollar-risk budget before using the sizing result.

Risk per share
Theoretical units
Capital required
Planned price risk
Unused risk budget

Complete the numerical inputs to identify the binding ceiling.

Still unconfirmed: source and freshness, setup-derived invalidation, execution and no-trade conditions.

Visible synthetic example

The lower ceiling can leave part of the risk budget unused.

Assume a hypothetical long-share worksheet—not a current security or market quote—with a 50.00 USD entry, 49.20 USD thesis invalidation, 80.00 USD dollar-risk budget, and 4,000.00 USD maximum-capital ceiling.

Planned risk per share50.00 USD - 49.20 USD = 0.80 USD
Risk-budget ceilingfloor(80.00 USD / 0.80 USD) = 100 shares
Capital ceilingfloor(4,000.00 USD / 50.00 USD) = 80 shares
Lower theoretical ceiling80 shares × 0.80 USD = 64.00 USD planned price risk

The capital constraint binds first, so 16.00 USD of the selected risk budget remains unused. The lower 80-share result is still not permission: stale source data, an invalid setup, spread, liquidity, portfolio exposure, or an event can make no trade the completed result.

Role comparison

Worksheet, checklist, broker preview, and protected review answer different questions.

This comparison prevents a calculated number or broker preview from being mistaken for thesis validation, suitability, or trade approval.

How the template reaches a result

  1. Validate direction.For a simplified long-share example, invalidation must be below entry. For a simplified short-share example, invalidation must be above entry.
  2. Calculate price risk.Use the absolute entry-to-invalidation distance as planned risk per share.
  3. Round down.Divide the dollar-risk budget by risk per share and round down to a whole share.
  4. Apply capital.If a maximum capital value is supplied, use the lower of the risk-sized and capital-sized share counts.
  5. Keep the stop conditions.Zero shares is a valid outcome. A positive number remains a ceiling that still requires execution, portfolio, source, and suitability judgment.

Why the result cannot guarantee maximum loss

The SEC explains that a triggered stop order becomes a market order and that the execution price can differ significantly from the stop price in a fast-moving market. A stop-limit order controls the permitted price but may not execute. FINRA's day-trading risk disclosure also warns that volatile markets, halts, system failures, commissions, margin, and short selling can create substantial or greater-than-initial losses.

IBKR's Check Margin feature can preview estimated commissions and margin impact before transmission. That account-context check belongs after the written review; it does not turn the worksheet into a recommendation or use up every dollar of buying power.
