Questrade vs IB for API

[AnotherBrian]

I have accounts with both Questrade and Interactive Brokers. I'm looking for thoughts, or more of a confirmnation, that the IB API works better with Medved and is also better supported than the Questrade API.

Questrade issues - On Medved, I enter a GTC stop order for a US market stock, and the next day when I check the stock, the order does not show up - but it does show up in the Questrade software. The Questrade trailing stop order are also not working correctly in the API (they do work in the Questrade software) - already discussed on this forum. It seems I also need to refresh the account often to get correct values - this scared the hell out of me since mistakes will cost me large $$.

So, any comments? I am seriously considering moving my funds to IB just based on the quality of the API to Medved Trader. How stable and accurate and reliable is the IB API to Medved?

IB has its own quirks but should be smoother. One thing - IB no longer lets you trade Canadian securities via API. Questrade does (via MT)

Yes, I learned this by mistake, thanks for confirming. Inside a registered plan (LIRA, RRSP) - there's no tax paid on capital or dividens on US stocks, so not many reasons to stay away from the US market for a registered plan other than any other regs. So I'll trade the US market.

Are there any issues/quirks I should look out for with the IB API?

max 100 symbols (but that is more than Questrade). Make sure to subscribe to the US exchanges. Level II though available, is not good via API.

The problem for lvl2 with IB is  that only Total view is usable, so if you plan to use lbl via IB api, subscribe only Total view.  (If you use lvl 2 via TWS, the  is ok because their windows aggreagate all lvl2 subscribable options )
