Hi,
I just finished implementing my solution and will go into testing mode in the next weeks. I am a software engineer and the solution is programmed by me.
Below are a few details but bare in mind the context: I'm an individual trader not an institutional trader (matters for the solution on the IB side)
Here is the part of the implementation:
- TradingView will send a request to an API hosted in the cloud. The handler of the request performs various validations and if all is good enters a message in a queue
- the queue is processed regularly and if all conditions are met (units, risk, orders or positions already open on instrument etc) an order is being sent to IB
The biggest problem in all this is actually maintaining a valid session with IB on the back-end side. They are behind current standards when it comes to web technologies.
My solution uses the client portal gateway which is rather unstable and they reset the session more often than the documentation says they would.
The login for the session is paired with a two factor authentication so if the session is reset you need to approve the session with your phone. The TFA can't be turned off.
However, often times the reset happens during night and there's nothing to be done there as you can't approve the session during sleep. Without a valid session orders can't be placed.
For institutional traders the protocol used for the session is OAuth and this allows for easier session management but I'm assuming you need to have a company. As far as I know TFA is also optional for institutional traders but I would NOT advice to turn it off.
I have been told by customer service that an OAuth roll-out for individual traders is planned but the road map is not clear.
An alternative would be to implement a different solution based on the IBGateway product but this involves coding very IB centric code which for me is not an option as I want my system to be as much as possible broker agnostic.
If you have any questions, feel free to post a reply.
Best of luck!
