What do the pros prefer?

What do the professional traders and veterans on this forum tend to use to for trading and checking charts.
MT4 or Ctrader or is there something else the big boys tend to use.

As far as I know, MT4 is the most versatile platform out there. It’s easy and intuitive to use and has plenty of functions that give you full control over your trades.

Banks use mostly Bloomberg and other specialized packages. But Bloomberg cost about $24,000 a year.

Retailers mostly use MT4.

I’ve heard that they use higher time frames in order to look at the market picture. Also they have some insider news from some paid news website or channel to decide about buy/sell prior to retail traders.
