I had a trialsof Proquote a few months back and found that it had some excellent features, however the TA package was a little thin on the ground.
I also encountered some problems with connection and the level2 screen crashing a couple of times when moving between stocks.
On the whole Proquote is a good system but doesn't provide the charting power I need as well as being extremely expensive.
I love it! Gives me all I want including Level 2, (at an extra cost)
My criticisms may seem minor. The Charting package does not allow for data intervals of less that 1 day in Historical charts. I therefore have Stockpoint.com up and running to look at monthly charts with hourly candlesticks. For trending markets the Linear Regression with Standard Deviation displayed is good. However they did have Envelope analysis as an option, but that has now gone.
For me, if you are serious trader you need Proquote. (I'm not on commission, just a satisfied customer)
Brilliant. Having used Reuters, Bloomberg ( still using) & Royal Blue's Fidessa professionally for last 17 years, Proquote is something of a revelation to me. It's intuiitive, acurate & relaible- everythign I need.
