Struct ActivityTrade 

pub struct ActivityTrade {
    pub market_id: String,
    pub asset_id: String,
    pub trade_id: Option<String>,
    pub price: f64,
    pub size: f64,
    pub side: Option<String>,
    pub aggressor_side: Option<String>,
    pub outcome: Option<String>,
    pub fee_rate_bps: Option<u32>,
    pub exchange_ts_ms: Option<u64>,
    pub source_channel: Cow<'static, str>,
}

Activity events still carried inside WsUpdate::Trade / WsUpdate::Fill. Retained as a typed payload alongside the stream rather than as a separate per-token surface.

exchange_ts_ms is exchange-authoritative millis since epoch — uniform with WsUpdate::{Snapshot, Delta}::exchange_ts, so every timestamp on the WS surface is the same type (u64 millis). chrono::DateTime was more expressive but cost a representation mismatch at every FFI boundary.

Fields

market_id: String

asset_id: String

trade_id: Option<String>

price: f64

size: f64

side: Option<String>

aggressor_side: Option<String>

outcome: Option<String>

fee_rate_bps: Option<u32>

Fee rate in basis points (e.g. 0 = no fee, 200 = 2%). Polymarket last_trade_price events populate this.

exchange_ts_ms: Option<u64>

Exchange-authoritative timestamp (millis since epoch).

source_channel: Cow<'static, str>
