Quote from Bob111:
wow..ok..since you start throwing some fancy words like "expectation" and all that shit, i'm going to try this:
here is how the process goes for me: thru the day,while i trade at same time i observe the markets,individual stocks,etc..the observations then became a trading ideas,that i backtest on the data from the past.it's a long and boring process,which those 99% of losers are trying to skip..the results of this process can be positive or negative..or simply not good enough for me..in some cases this process can take a YEARS..once i have enough data samples that confirms, that my idea is profitable and does have POSITIVE expectation-then and only then i will put some(not all,not on margin X4) of my money to trade it.
now...this doesn't mean that this "system" will last till rest of my life. the "edge" can stop working at any time. but same rules applies to any real job in real life. there is no guarantee, that you are going to flip the burgers till rest of you life. new manager can fire you at any time.that's why me, while been a trader is constantly looking for an ideas and spend a large amount of time on research,development and education. it is extremely boring evolutionary process..think about this-you go to a evening college every day till rest of your life..having multiple "systems" with positive expectancy will literally guarantee that you are going to make the money every month and every week and in some cases EVERY fucking day. but. like i said above-it's not an easy job..and it certainly not for everyone.but creative person,who can observe the markets and come up with his own ideas,extracted from pretty much 3 numbers such as bid\ask\last will survive. and there is nothing about luck in this process..it's mostly statistics and math.
