Good day guys! i need your honest suggestions.

i am a binary options trader that trade using Trade Interceptor (a charting app similar to metatrader) on Android phones/tablets.

Now my strategy requires that i use the info provided on the chart to place trades on my broker. that means i have to switch from the chart to my browser extremely fast (a second is extremely important to a binary trader). To make up for this and be on a very safe side, i use two android devices (a tab [samsung galaxy] and a phone [tecno p5]). I watch the charts on the tab and place trades on my p5.

However, this is so uncomfortable for me because i not only look weird looking at 2 devices at the same time, i also have to put on the hotspot of the p5 to enable the tab internet-wise, so its battery gets drained easily.

A friend recently told me of android devices that can do multi-window tasking - that means opening more than one app or windows on your android device just the way you would do on pc. an example is the LG Primus V2 or so. i got really interested

i would be glad if anyone can suggest at least a 7inch android tablet that can do multi window tasking to me i would be most grateful. i attached a photo to buttress my point

how it looks like

.

i would be glad if the recommended tabs are within the price range of 25-35k
