bitcoinwisdom can gives you maximum of 1 minute updated chart.. There is other chart that i think could be work in seconds updating chart.
If you know sparkprofit i am using it just to learn trading before and for trading margin the good thing there your points could be convert into bitcoin if you are success to analysis the movement of the price of bitcoin ..
I don't see any other site that we can see ore faster present accurate updated chart as of now compare to the bitcoinwisdom ..
I’ve used bitcoinwisdom.com and highly recommend, but this is a browser sites and no mobile app available, it is really not for me. Sparkprofit and HIQL are good too and has mobile app so I think it will be a better alternative for and it is really a good practicing platform for trading but it just that it works will to those who invest more.
Now I’m a travel guy, so mobile application is a must. Bitcoin ticker is what I’m using now and it works perfectly fine. There is also many option, if only you buy the pro version/subscription. But free version is good enough.
