● Toolkit

A small toolkit, free to use.

A Claude Skill that tests your own trading idea to a numeric verdict, and three calculators that answer questions worth answering before a trade. Everything here is free, and there is nothing to sign up for.

Strategy tester: a Claude Skill for your own trading idea. A free Claude Skill that takes your own trading idea from a hunch to an honest GO or NO-GO, with the backtest method written down first. It carries the method and leaves the idea to you. Get the skill ↗ Position size, from the risk you chose. Work out position size from account equity, risk per trade and your stop distance — and see what the round-trip fee costs you as a share of that risk. Open the calculator ↗ When a funding carry starts paying. How long a delta-neutral funding carry must be held before the funding collected covers the four fills it takes to open and close both legs. Open the calculator ↗ What a drawdown asks for in return. A drawdown and the gain that undoes it are not the same number. Work out the recovery a given drawdown demands, and how long it takes at a steady return. Open the calculator ↗
