Frequently Asked Questions

Are all tools free?

Yes. Every calculator and tool on this page is free. No account required. No credit card. The tools use the same prop firm data that powers Vigil audits, so the rulesets and limits are always accurate.

What is the most important calculator for prop firm traders?

The position size calculator and drawdown calculator. Position sizing determines whether a losing trade stays within your daily loss limit. The drawdown calculator shows how many losses you can survive. Together they prevent the most common cause of account failure: oversizing.

How is the trailing drawdown simulator different from a regular drawdown calculator?

A regular drawdown calculator shows cumulative loss from starting balance. The trailing drawdown simulator shows how trailing rules (EOD or intraday) move the drawdown floor as your equity changes. This matters because a profitable trade sequence can actually reduce your buffer on trailing accounts -- something most traders do not realize until they breach.

Can I use these tools without a prop firm account?

Yes. The tools work for personal accounts, demo accounts, and any trading strategy. The prop firm presets are a convenience -- you can enter custom values for any field.
