Hi Intrepid,

Thanks for the comment I am glad you like the site and welcome to the community.

I am not familiar with Just2Trade so I cannot comment one way or another on them. If there is anyone who is I would appreciate it if you could provide some insight here for us.

As far as free charting packages go many brokers will give you access to free realtime charting once you have an account so the first place I would check is with the broker. If they do not have an offering that is to your liking then you can find some additional information on free charting packages at the link below:

As far as knowing which stocks are going to have high volatility before the market opens like anything with trying to predict market movements there is no way to know for sure. Obviously however if news comes out about a company overnight that seriously affects earnings one way or another or things such as this then you are likely to see that stock move pretty dramatically during the day.

If there is anything else on this one from anyone please feel free to post it below.

Best Regards,
Dave
