System X 80 Percent Winners
Whenever I see a trading system claiming to have up to an 80 percent rate of accuracy or winners I personally become quite skeptical. If system X claims to win almost 80 percent of the time it may not be a very profitable system. If you were to win 8 out of 10 trades (80 percent winners) and your average winning trade is $500 then you have a profit of 8 X $500 = $4000. If the average losing trade is $2,000 then you have a loss of 2 x $2000 = $4000. Now if I win $4000 on 8 trades and lose 4000 on the other 2 trades I breakeven, because $4000 - $4000 = $0. Do not forget about the commissions. Now system X is a loser.
System Y 40 Percent Winners
When I look at a system that says 40 percent of trades are winners I am more interested because that system is probably not curve-fitted. If you were to win 4 out of 10 trades (40 percent) and your average winning trade is $2000 then you have a profit of 4 X $2000 = $8000. If the average loser is $700 then you have a loss of 6 x $700 = $4200. Now if I win $8000 on 4 trades and lose $4200 total on the other 6 trades I should win, because $8000 (winners) - $4200 (losers) = $3800.
Clearly it can make more sense to trade a lower percentage wining system that has more profits than to trade a higher percentage winning system that may breakeven at best. It is unfortunate that some system developers try to look for a high percentage winning system to attract the public with potential false hopes. I illustrate this because of the Holy Grail that so many traders are looking for and only to find that the high winning percentage Grail does not exist.
Commodity Inflation
With commodity inflation present it makes good sense to look at trend trading commodities for diversification in ones investment portfolio. It is very important to have diversification amongst the many commodity sectors including; Grains, Metals, Fuels, Currencies, Bonds, Foods and Fiber products.
I like the Trend Simplicity suite of commodity trading strategies
approach to trend trading the commodities markets. I prefer trading systems that are not curve fitted and that go for the larger trend moves. The commodities markets have had very big moves recently with the lower US Dollar and commodity inflation. Just think if you would have had an opportunity to enter Gold or Soybeans, Wheat or Crude oil a couple of months ago or several months ago.
