Support for Midprice and IBAlgo orders

[rmalh]

Describe Enhancement

I tried using OrderRequest() with order_type = 'MIDPRICE' and 'ADAPTIVE' (one of IB's proprietary algos), but it doesn't seem like iBind supports them. 'MIDPRICE' threw error "orders request includes parameter with incorrect type" and 'ADAPTIVE' threw "OrderRequest.init() got an unexpected keyword argument 'order_params'".

Context

I currently use limit orders but would like to evaluate these algos for my trading.

Possible Implementation

for MIDPRICE: orderType = "MIDPRICE"
for ADAPTIVE: algoStrategy = "Adaptive"; algoParams = []; algoParams.append(TagValue("adaptivePriority", "Normal"))

Your Environment

• IBind version: 0.1.22
• Python version (e.g. 3.10): Python 3.13.7
• Authentication method (Gateway, IBeam or OAuth): IBeam
• Operating System and version: Ubuntu 25.10
• Link to your project/code (if public)

Hey @rmalh thanks for outlining your issue.

I suspect this may be not IBind, but IBKR rejecting it.

To start with, I couldn't find "orders request includes parameter with incorrect type" anywhere in IBind. I believe this is a response from IBKR, indicating the request may have malformed parameters.

As for the order_params not being supported by the OrderRequest: please specify them as custom_fields, eg.

OrderRequest(...,
    custom_fields={'order_params': {...}}
)

This field is specifically provided for supporting custom parameters like you're trying to.

Let me know if these help 👍
