I have just started reading more and I'm definitely going to start trading. I also just opened an account with my bank but the cost of each transaction is quite high compared to other trading websites. i will keep reading before i buy anything though.
A few dollars won't make huge difference.
In the beginning you won't be don't millions of trades per day.
Trade a few companies a day and hold some for longer periods. But be minimistic and just learn the basics wallahi. 5k is the best to start with. And you want that 1-2 companies per day
