Constant Range Bars Broker

Hi

Ive searched and searched for a UK based broker who offers a platform with constant range bars (NOT ON MT4!). I have tried all types of CBRs on MT4 platforms and there are lags or delays.

Any recommendations ?

check the vertexfx platform

Ive not checked out vertexfx platform as its not with any registered UK broker.

Any other people use CRB in UK ??

LMAX + sierra chart.
LMAX + Alphatrader (alphaNovae UK)

Thanks Duxis

I like the look of AlphaTrader but the website and stats haven't been updated

Sierra chart was something I also looked at but it is a large investment when moving my code from MT4 (im not a great coder!!)

I am also reviewing Amibroker and trying to plug in a datafeed from MT4
