> I wanted ("buy at MACD crossing, sell at 3% profit or 10% loss"),
This is a troubling statement to me. Why would anyone in this world want to take over 3 times the loss vs. a win? Your win rate has to (realistically, before transaction fees) maintain an 80% rate in order for you to have a winning system. It's NOT about how often you win. It's about this: Expectancy = (prob. of a winner) * (avg winner) - (prob. of a loser) * (avg loser) If the expectancy is not a positive value, you will lose at this game. Look for systems that give you a 2:1 plus advantage of your winners over your losers. The higher that ratio, the more losses you can take. The trick is to take those small losses relative to the big gains in order to finish profitable after a long series of trades. For example, I have a an ER2 swing system that wins, on average, around 40% of the time, but the avg winning trades maintain a 3:1 advantage over the avg losing trade. Believe me, it's no fun emotionally watching a system lose multiple times in a row, but when you have this kind of expectancy: Expectancy = (0.40 x 3) - (0.6 * 1) = 0.60 [here, "3" represents $3 for an avg. winner and "1" represents $1 for a avg. loser] It means, in relative terms, that you can expect to see 60 cents returned for every dollar invested. I would never, ever, EVER be willing to lose more than I intend to gain. It is a rookie mistake in this business to focus on a high winning percentage as a primary factor in being successful. You should focus on taking good risk/reward opportunities and be willing to accept losing (a lot of the time) in order to win overall. I realize this is an Amibroker thread, but please, remember that it is only a tool and if no one ever tried to step in and get you to think beyond the mechanics of using this tool, it would be a greater disservice than saying nothing at all.
