Not very reliable. – StoneX iBroker Review

The App is just OK. No features like trailing stops or bracket trades. But the market feed is unreliable. I put in a market trade only to find out the feed was down and my order could not be canceled. I waited for a half a day to find out what financial damage was done to my account. If you use this App have your broker on speed-dial.
