The free service is good enough, the paid service is a bit expensive in the era of the internet. If i had to pay I would rather pay for tradingview, the learning curve is a bit steeper but the charts are excellent and the monthly rate is cheaper, However. I have free accounts on both as I don't think i should have to pay for what is essentially free data. The only novel aspect here is the charts and that should not cost more than 9 bucks a month
