I have given novice traders complete stand alone trading systems that have 1 to 1 risk to reward ratio's and time proven 70% win/loss records. Every single time that I have done this for someone, I have found that newbies lack the discipline and intestinal fortitude to follow through and stay the course with those trading systems. I have had newbie friends win 7 trades in a row, followed by 2 consecutive losers and quit trading because of the 2 losers. They can't emotionally handle losing. It demoralizes them and then they don't trust the trading system and that causes a breakdown in discipline, which leads them to give up. In my opinion only a very small percentage of people are equipped with the physiological tools necessary to trade successfully.
To answer the original question, only an idiot would share a strategy that works. Anyone who doesnt understand why, is an even bigger idiot.
<i>"To answer the original question, only an idiot would share a <b>(mechanical system)</b> strategy that works. Anyone who doesnt understand why, is <b>(ignorant to the realities of real-time, human trading)</b> an even bigger idiot."</i> With a little bit of editing, this statement now reads correctly
Are you saying that non-mechanical systems are immune to saturation? I dont see how that is possible. For any given strategy, there is a finite price range and shares in that price range where an instrument is mispriced. Throw enough people into the same boat and it will sink. Non-mechanical, makes things "fuzzier" and the "edges" of what is considered the strategy is not nearly as clear as a mechanical system, but the same exact thing will happen. It will become overloaded and worthless.
I suggest that you read Van Tharp, "Trade your way to Financial Freedom". Talks about how to develop a successful trading system. For example, the entry is the least important part of a system. He demonstrates how you can use a random entry and still make money.
For me, the entry is the most important part of a system followed by money management. Each to their own!
