I'm using the TWS plugin. I can't figure out how to get current cash from the broker. Any suggestions?

You can use SystemData.Broker.GetBuyingPower() to get the buying power.  This should be some multiple (depending on your leverage) of your cash when you have no positions open.  There's not a simple way to get the actual cash right now.  If the buying power isn't sufficient for you, we could probably add an option to the TWS plugin to return the actual cash instead of the buying power when GetBuyingPower is called.

Thanks,
Daniel

I replaced buyingPower with NetLiquidation within TWS Plugin source code, but I would like to concentrate on strategy coding instead of extending trading platform functionalities.
My suggestion is to add such a basic informations like Cash Balance and Unrealized PnL to the system. OpenQuant has this and it's important for calculating order size based on money management system.

Fully agree with the OP. Why cutting down on the functionality IB or others provide through their API. If providing a wrapper rather than the original broker api why not parsing the most important and most often used functions instead of simply excluding them? Current cash balance or net liquidation value is in my humble opinion a much more important metric than even available margin/ buying power.

When we built RightEdge, one of the philosophies we had was that systems shouldn't depend on a specific broker. They should use generic code that would work with any broker there was a plugin for. That's why there's not an easy way to access all of the functionality that TWS provides.

I think user feedback has shown that we weren't entirely correct with that philosophy. For some customers at least, it is important to be able to access broker-specific functions. So as we move forward we will likely try to make it easier to do this.

Thanks,
Daniel
