I did not have problems with FX blue so far. Did you succeed to synchronize your account with the website?
If you did it should not be lagging, with every click on different section or with refresh on the browser, you should see the new results.
Also, make sure you have closed trades in the account, and not only opened trades. The statistic will update when there are new closed trades.
Once again I had no problems with FX blue so far, but it could be somehow frm the server of your broker..
Let me know how it goes
