Cherry, this is something I know a lot about. I have used and still use IG custom nets every now and again... The reason you see the position close 17 hours later than the official close is that believe it or not a huge company like IG still settle their custom bets manually. They do not get many wrong but it is a slow process.
I know you guys are very experienced and all make great profit but 85% is not a great deal for a one day trade.
As I said I use them still as the platform is easy to use so good luck with IG you are in good hands.
its true, 85% is not a great deal specifically to binary options. personally i have often turn $250 into $10K in a day and couple of times into $20K.
but 85% for a trade per day is absolutely fine with me. With a decent amount of capital, it is quite a feat. And in this case its hassle-free fire and forget kinda of trade for me. So the payout is highly acceptable.
