Error message

Unsupported TIF {time_in_force} for MARKET on Coinbase (use IOC or FOK)

What it means

When converting a MARKET order to Coinbase's Advanced Trade API payload, only IOC and FOK time-in-force values are supported (mapped to MarketIoc/MarketFok configurations). Any other TIF on a MARKET order is rejected by the payload builder.

Solutions

1. Set time_in_force to TimeInForce::Ioc (or Fok) on MARKET orders sent to Coinbase
2. Leave TIF unset so the adapter can map the market order appropriately if supported
3. Adjust strategy/order-factory defaults so only limit orders carry GTC/DAY
4. Validate the (order_type, time_in_force) combination in pre-submit checks

Example fix

// before
let order = order_factory.market(..., TimeInForce::Gtc, ...);

// after
let order = order_factory.market(..., TimeInForce::Ioc, ...);

if order.order_type == OrderType::Market
    && !matches!(order.time_in_force, TimeInForce::Ioc | TimeInForce::Fok | TimeInForce::Gtc)
{
    return Err(anyhow!("Coinbase MARKET orders need IOC or FOK"));
}

When it happens

Trigger: Submitting a MARKET order whose TimeInForce is GTC, GTD, DAY, etc.; typically from a config that sets a default TIF globally without considering order type.

Common situations: Strategy defaults TIF=GTC for all orders; a routing layer that stamps DAY on market orders; porting orders built for venues that accept GTC market orders.
