ProRealAlgos · ProBuilder
A real ProBuilder interpreter and order simulator, in the browser. The bars are synthetic and seeded, so unlike any real chart, the correct answer is knowable: some of these series carry a genuine edge and some are pure noise. Find out which after you have made your call.
This is a strict subset of ProBuilder, never a superset. Nothing here is invented and nothing is made more forgiving, so anything that runs in this playground is valid code in ProRealTime. When you write something outside the subset the message says so rather than calling it a syntax error. One bar is one hour from midnight on Monday 1 January 2024, so the clock instructions carry real values. Execution is modelled, not replicated: market orders fill at the next bar's open, stops and limits fill intrabar on the next bar, and one spread is charged per side. Your platform results will differ in the detail. The concepts are what transfer.
