When you're just starting trading and do not have consistent results, your aim must be to survive in the game, to not wipe out your account. This probably means very small trades so that even if you have big winners in %age gain terms, the financial profits will probably be very small. So this cannot be an income during your learning time. But the objective is to have losers that are only a very small %age of your account, not to have winners that are a very high %age, that will come after you area consistently winning. The idea is to stay in the game long enough to learn its rules.
Understanding market behaviour and entry points from charts, etc. can be done well using demo account or donated money, but during this phase you are not learning much about yourself, i.e. how you will feel and react when in a trade and trying to manage it to completion. This has to be done with your own real money, probably which you have worked hard to gather together into the account and maybe the work was horrible and you even had to pay tax on poor money from a cr@p job. But that will just make your reactions more honest and real when you're in a trade.
This is important because it is the exit that is going to pay you, not the entry. And although all the world might see the entry signal on the chart, only you decide when to exit. The entry is you paying a deposit to the market. So if the trade goes into the money, how will you react? -
will you be frightened and get out with a tiny profit as soon as you can?
will you lie awake at night wondering if you will be gapped tomorrow morning and go back to entry price?
will you stop looking at the chart and just hope next week it will have gone your way by 100%?
And if the trade goes aganst you, how will you feel? -
will you panic and exit at the first volatility?
will you double your position size?
will you push your stop wider?
will you stop-and-reverse on the same market?
will you just stare at the screen when you should be asleep / doing other trades?
You will need to know / feel the answers to these questions and they won't come from a chart or a demo account or from trading someone else's money. We actually need to take some risk in order to become good traders and those risks will mean taking some losses. Without risk and losses, you will not last long enough to have wins.
