Before simulated entry
Use these tools before paper entries to check whether a plan fits the written setup and simulated risk limit.

Paper trading tools and calculators
Use these calculators to make simulated trading decisions reviewable: planned paper size, risk-reward, max drawdown, and overall paper risk. The output belongs in a checklist or journal, not in a live-trading order ticket.
During risk review
Use risk tools to review drawdown, related exposure, and whether repeated small decisions are creating one large paper risk.
After the sample
Use the numbers as evidence in a journal or benchmark review rather than treating a single ratio as proof.
Tool selection guide
| Question | Tool | Review context |
|---|---|---|
| How large should the simulated position be? | Position size calculator | Use with pre-trade review before entry. |
| Does the target justify the planned stop? | Risk-reward calculator | Use with thesis notes and target realism review. |
| How deep was the simulated decline? | Max drawdown calculator | Use with benchmark reports and risk controls. |
| Is the paper workflow taking too much risk? | Paper trading risk calculator | Use with exposure, frequency, and drawdown notes. |
Example calculator workflow
Plan: The trader records a simulated entry, stop, target, and paper risk limit before the trade.
Tools: Position size checks the paper size. Risk-reward checks the target and stop. Max drawdown is reviewed after several samples, not after one entry.
Output: The numbers are saved in the journal so post-trade review can compare plan, behavior, and outcome.
Calculator limits
Calculators make assumptions visible, but they do not include every real-world factor. Fees, liquidity, slippage, fill quality, emotional pressure, and regime shifts are outside the simple math.
That is why every tool links to a workflow or template. The calculator result is an input to paper-trading review, not a decision engine.
Educational use only
Trading Boy calculators are educational tools for simulated paper-trading review. They do not provide financial advice, live trading instructions, or outcome guarantees.
FAQ
What are these tools for?
They help plan and review simulated trading decisions with consistent math.
Do calculators recommend trades?
No. They provide educational calculations for paper-trading review.
Where should outputs go?
