Live Execution

Change a running strategy's parameters

Changed on

Updates one or more parameters of a run while it stays live — unlike params on POST /strategy/{strategyId}/live, which only sets the starting values. Owner only.

Every key in params must be one your strategy declares (see declaredProperties on POST /strategy) as of the compilation this run is executing — recompiling the strategy later never changes what an already-running instance accepts; start a new run for that.

The change does not take effect the instant this call returns: effectiveAtMs is the earliest moment it is guaranteed to apply, a few seconds out, so both the REST and WebSocket paths to this same update (see the "Live execution" guide) land on the exact same value at the exact same moment.
