📈 Order Book & Matching

Place your own order into a live order book and watch the exchange work through it: which resting order it hits, at whose price it executes, what is left over and where that remainder goes. Five models cover continuous matching, the ATO/ATC call auction, time priority when you amend an order, the order lifecycle behind every ExecutionReport, and the price band, tick size and lot rules that reject an order before it ever reaches the book — each step lit up beside the matching line of Go and TypeScript.
