fyi, when I made the comment that bloomberg is the most widely used software, perhaps that was inaccurate statement. But to clarify, i meant that nearly every trader on the street at every major institution across the board uses bloomberg on the buy and sell side. Moreso than any featured software on this forum.
In regards to the functionality,
its not as fast as amibroker which is what i am currently playing around with in regards to backtesting. Its well inferior to AB, but i think bloomberg is going to make great attempts to beef up this functionality. It does have a study editor which can allow you to edit your entry/exit points intuitively but its opened up this up to C sharp and vba users to program in their respective codes.
The backtesting so far seemed to have problem with loads of intraday data, and can only be run to one security at a time. but perhaps i am not doing it properly.
However, bloomberg's other division tradebook can allow the user to reprogram the results in excel vba for example and send signals trhough its proprietary API softare. So if you backtest in BT, run simulation via excel vba and tradebook. you can do move into execution.
i assume the API execution is very stable. Overall, i think bloomberg will surpass CQG in this area and for some hard core programmers that still like write in its own code can be used as one stop shop IDE. but this is some way down the line.
