I use IG. They’ve added trailing stops, if you use them. Overall, I’m very happy with them, and their charts are better than MT4, IMO.
I also have used Forex.com and they’re great, but their charts are horrible. What I like about Forex.com is their orders. They have OCOs, which come in handy. Also, their platform automatically converts the SL risk into USD. IG doesn’t do that–it only tells you the risk amount in the base currency. A small detail, but when trading frequently, it’s one less step to calculate.
There was a time I had multiple accounts. I used IG’s charts, and also traded on Forex.com
I didn’t have any problems. Their numbers are quite similar and I never had any discrepancies between the two. However, I trade D1 so my stops are quite wide compared to H4 or faster charts.
