Did you ask your broker ?
Can you please demonstrate your issue, with screenshots or whatever ?
What this screenshot is supposed to demonstrate ? With Forex, you can never expect to get the same price feed from 2 different providers, it's not a centralized market. How are you evaluating the "lag" as 20-30 seconds or 3-4 minutes or ... ?
Hi Alain, thanks for your comment. I'm simply timing the the difference between both charts to reach the same point. I should apologise - the platform "graph" is not very useful as a comparison - particularly if you're not used to looking at them. I appreciate that there is a difference in price between different platforms/providers/brokers, etc, but when that price difference is so wide (compared to what has been the norm for my two years of experience trading forex), and there is such a marked delay in one chart reaching the same point on the other (using features such as spikes, etc as a guide), I have to query "why". As I mentioned previously, I have never seen this before. And it just started a few days ago, hence wondering if there has been a change to MT4 or something else I'm not aware of. If the time lag was consistent at least I could understand that. But it seems to vary at different times of the day, and when the difference is over two minutes, there must be an issue somewhere, surely. I guess I'm simply looking to see if anyone has experienced anything similar and perhaps a suggestion or two as to what I could do to solve the problem.
