DislikedIn my opinion, you should continue to use your live account but forget about making $100/day for now. Reduce your lot size so you are trading pennies per pip. At one point in time, I traded .01 micro lots, a penny a pip, for 2 months.
My reasoning for this is not so much that the data feeds are different on demo accounts (they are) but trading demo removes the FUD factor (fear, uncertainty and doubt). FUD is a thing you need to learn how to deal with as a trader (read Trading in the Zone). If you are trading very small lot sizes, you at least have some emotional involvement in the trade. As your results improve and your confidence grow, you can slowly increase lot size.
Just my opinion...other may think this is a crockIgnored
Anyway using smaller lot might help especially when dealing with FUD... what broker do u use actually?
