1. Generally trading platforms have limititations on number of market watched that could be opened. How much do u intend to open.
2. Even in each market watch there is limitation on number of scrips that could be added. How many u wana watch in a market watch.
3. How many intraday charts do u want to keep open.
Assume he has market watch in one full monitor. He can keep intraday charts in second monitor and third will be for live market news feeds from bloomberg or reuters or something.
My thing is, in US, FRANKFURT they trade 3-8 monitors with the buying power of half a million to xxx million. It seems to be fine for them trading with x no. of monitors. But for individuals with less capital this seems to be unnecessary. (This is just my view, don't take it hard - opinion differs)
4. Which trading platform in india will actually support showing up on multiple monitors.
I am not sure about this. I haven't tried any or seen any. But my guess is there will be.
Last month i saw a link where i saw around 10 monitors connected to systen by intraday trader in US.
I haven't seen a trader with 10 monitors, yet.
