First computer that took humans to moon:
Computer recommended by Zerodha for trading on pi:
If it still does not work, you will need a Satellite Broadband.

Yr system requirement depends on
-
yr trading style. For example if u r comfortable seeing charts U need two monitor. Some do very well with only laptop and 3G connection

Your internet connection speed. If i want to have an i7 quadcore then broadband speed of min 16 mbps is appropriate.

For 20k best option wud be a tab with min 4 gb ram, 2 mhz + chip and excellent screen resolution

Great trading experience: i7 quadcore, 16 gb ram, 2 nos. of LG ultrawidemonitors & 40 MBps broadband
