Hi.
If I could just add my thoughts here.
I'm in a similar position, I'm 23 years old, live at home, still at uni, and have just started with $46k trading equities using a mechanical system on the ASX.
(I actually have traded in a discretionary manner for about 2 years with mixed success, hey, its a bullmarket).
I will start full time work soon, so my system is a weekly system which is trend following in its nature.
The difference is between my approach and yours I suspect is that my system has been backtested over different market conditions and has been proven to have a positive expectancy.
Backtesting will provide you with a blueprint of what to expect during live trading:
*What is maximum DD?
*How is my system likely to perform in a bear or sideways market?
*Position sizing strategies can be easily evaluated?
*Largest string of losses.
*Etc, etc
With no blueprint obtained from backtesting, you have no idea how your system will perform in realtime and if it will even be profitable.
The problem IMO with discretionary trading, unless you are very systematic and disciplined with your approach, is that your trades are controlled by fear and emotion, which are often irrational.
Im too scared to deviate from the plan that was backtested because then im pretty much trading blind!
At the same time no point to stick to a plan if you dont know if it is even profitable. Is backtesting perfect? No. Is the future the same as the past? No. But for young people like us with a limited track record and no idea if our system is likely to be profitable, its the best tool we have.
I have maintained a blog regarding my systems development and my live trading and it may be of interest to you.
