From your phone to the exchange — Journey of an Order | In the Money by Zerodha

In this episode, we explore something most traders never think about — what actually happens in the two seconds between hitting buy/sell on Kite and seeing your order confirmed. I'm your host, Sandeep Rao (SEBI Registered Research Analyst – INH000013059). From the moment you tap buy on Kite to the moment the exchange says complete, your order travels through CloudFlare's security layer, AWS's load balancers, dedicated P2P lease lines, physical data centres in Mumbai and Chennai, three layers of internal checks — a mini RMS, the OMS, and the main RMS — and finally to the exchange itself. Seven layers. Hundreds of moving parts. A few milliseconds. This episode also examines what can go wrong at each stage — from CloudFlare false positives that block legitimate users, to lease line flapping, to the rarest and most disruptive scenario: the OMS or the exchange itself going down.
