# Free tools overview

Free tools on tradesurge.co that need no account - check your odds, size your trades and compare firms.

The free tools live on `tradesurge.co` and need no sign-in. They answer the questions a prop trader asks before buying a challenge. Everything you enter stays in your browser session.

## Check your odds before you pay

The Eval Simulator runs your trading numbers against a real firm's rules 1,000 times. It shows how often you pass, how often you breach and how many days a pass usually takes.

## Size every trade in R

The calculators turn account size, risk and stop distance into an exact position size. They also explain the two rule families that end most accounts: drawdown and consistency.

## Compare the firms

The prop-firm directory lists 76 firms with their rules, payout terms and current deals. You can compare two firms side by side.

## Where the tools lead

The free tools answer questions about one account. The Platform runs the same maths across every account you hold, live, and enforces it before a trade fires.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.tradesurge.co/free-tools/free-tools.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
