First thanks.
I use NT but in the last time I have some problems to load historical data in multiples charts.
I open 6 charts using diferent sessions time in each.
For example, I open ES in LONDON session (open and close london candle), etc,etc
I like to know if another platform have this choices of select time session for each chart.

I use think or swim for charting. Do not like the trade execution quite as much as Ninja, but the charting abilities are much better. I think with ninja you need to save data to your hard drive if you want to access more than three days back, however, as I currently trade on a laptop, I haven't tried it. You may want to contact support.
