Quote from kut2k2:
The number one determinant for trading success (aka long-term profitability) is a trading plan with consistent positive expectation. Without that you got nothing. Yes, lowering commissions will save you some money but it won't make you profitable.
The whole point of trading is to make money, not just prevent losing money. If the latter is your main concern, just put your money in your mattress. Zero commissions there.
Maybe we're talking about the same thing.
I have about 10 important variables in my trading plan and a trade signal is just one of them. Simply, trade signals are just one chapter in a book regardless to its location in the book.
A good trade signal can not compensate for a poor trading plan.

...And, yes, it does involve trade signals only. If it doesn't work in real money trading situations, then the testing was inadequate. Involving a lot of extraneous considerations merely clouds the issue and encourages the trader to believe he has an edge when he doesn't. The development of an edge is statistical, not philosophical.
I strongly disagree that an "edge"
only should involve trade signals.
You give me a trader with trade signals that show positive expectancy in their backtesting and then
ignores discipline, money management, proper capitalization, proper position size management, proper stress management, adequate computer, adequate ISP connection, poor commission rates and so on...
You're going to see a losing trader because all the other pieces in their trading plan weren't adequate or ignored in real trading.
A good trade signal can not compensate for a poor trading plan.
I have support about the above from the countless of trade journals here at Elitetrader.com and across many other trading forums where traders posted positive back tested results with programmers chiming in to say this is "good work".
Then the trader starts live (real money) trading their so called positive expectancy method and it
mysteriously doesn't make money. You know the drill and have seen these journals. Oh well, back to the drawing board. Gotta re-design those trade signals because its the only thing that matters while ignoring every thing else.
Maybe the issue is the word "edge" consider its origins and use is used in many different situations like sports, wars, exploration, social media and others.
Therefore, maybe there should be an independent thread that talks about "edge" because it really a philosophical discussion and a separate thread about "positive expectancy" that deals exclusively with trade signals and not anything else...
Makes sense to me.
