TPSL MARKET price type blocked by NotImplementedError despite API support

[fedarrdi]

Summary

create_order_object in order_object.py raises NotImplementedError("TPSL 'MARKET' price type is not supported yet") when OrderPriceType.MARKET is used for TP/SL triggers. However, the API documentation explicitly lists MARKET as a supported value for the priceType field on both takeProfit and stopLoss triggers.

Location

x10/perpetual/order_object.py, inside the nested create_tpsl_trigger_model function within __create_order_object:

if trigger_param.price_type == OrderPriceType.MARKET:
    raise NotImplementedError("TPSL `MARKET` price type is not supported yet")

This guard is present in all versions up to and including 1.3.0.

Why this matters

Stop-loss orders placed as LIMIT may not fill during fast price moves / gaps. Market-type SL execution is critical for risk management — the API supports it, but the SDK prevents users from using it.

Expected behavior

OrderPriceType.MARKET should be accepted and serialized as "priceType": "MARKET" in the API payload, the same way LIMIT is handled. The rest of the SDK (serialization, settlement signing) already handles MARKET correctly — only this guard needs to be removed.

Suggested fix

Remove the two-line guard:

- if trigger_param.price_type == OrderPriceType.MARKET:
-     raise NotImplementedError("TPSL `MARKET` price type is not supported yet")

Hey. Thx for raising. We will add MARKET price type support for TPSL next week.
