I recommend to start off watching the movement of stock market/s and stocks you like on an End Of Day time period. You can record this information in your head or on charting software such as Amibroker. There are free chart software but I haven't used any for so long I don't know what they are. Google anything you want to know. You can jump in with hard earned/saved money but I reckon the wolves will eat you. There are no friendlies in this game. It is cut-throat at its finest and less than half (so I have read) stay with it and survive or make some decent money.
Forex is the ultimate game of cut-throat. Price can swing wildly on anticipation one way and news in another and it can happen while you sleep if you leave a position open. On top of that, if you leave a position open then sleep is an issue because it is always in the back of your mind, what is the price doing. Has my stop been hit, am I in profit etc. Can be overcome but the stress isn't worth it. Google 'whipsaw financial'.
Remember RISK (and that amount is up to you) is what you deal with in both markets. You could die the death of a thousand cuts or lose it all in one go. Start with End Of Day (EOD) learning of stocks and see how you go.
