FYI, you can:
1) Kindly ask for free updates here on the forums. Sometimes they do it when they have manpower/budget to spare.
2) You can also pay for expedited changes if they have upside for your trading account. Trading is a business operation, after all, so it can make sense.
3) Write your own plugin. The broker API is documented here:
