Module `Algostream_analytics.Tick_event`

Normalized tick record bridging bus payloads (Market_tick / Trade_print) into the analytics pipeline. Field set is intentionally narrower than the bus payloads: only what the analytics layer actually uses, so the SPSC handoff is small and predictable.

type kind =

| Market
| Trade

type t = {

symbol : string;
timestamp_ns : int64;
price : float;
size : float;
bid : float;
ask : float;
kind : kind;

}

val of_event_payload : 
  Algostream_infrastructure_event_bus.Event_types.Event.payload ->
  t option

Convert from the bus payload. Returns None for payload variants we don't process.
