Why these
Almost every account that fails does so for a reason that lives in one of these calculations, and almost none of them fail for lack of a better entry. Sizing decides whether a bad run is survivable. Expectancy decides whether the system is worth running at all. The distribution of outcomes decides whether you will still be running it when the edge finally shows up. And correlation decides whether the risk you think you have spread across a book is one trade in disguise. Everything else — indicators, structure, order flow — is built on top of these, and collapses without them.
How they work
Every calculation runs locally in your browser. Nothing is uploaded, nothing is stored, and there is no sign-up wall — the tools work in full whether or not you ever buy anything from us. The contract specifications behind the position size calculator follow the published CME specs, and every tick field stays editable so you can verify the numbers against your own broker before relying on them.
