Did a little search on what's going on with data feeds and AMTD.
I 'found' QT back in the day, Datek was my broker. Loved it and have used it ever since.
Then AMTD bought Datek, I got moved over but everything seemed fine until this year.....
I love QT. I don't think I would trade without it! Yet data feeds are constantly poor lately, today, right now, no volume transfers. Charts are frozen because even though the ticks are changing, there's no data on what trades (volume) are taking place.
And yes, I too have noticed a VERY big lag on L2 vs L1. Sometimes L1 is right (real time) sometimes L2 is right, but the sync has been off for over a month!
I trade options and some swing trades with five minute timing and THIS SUCKS! I have no idea what's going on, but trading is hard enough let alone flying blind with frozen indicators.
I guess it's time to find a better software / broker system, I can afford it VS the loss I may have from poor data feeds.
