1.
 Always be skeptical about your own ideas, focus only on results. 
Sometimes is easy to track trading opportunities, what is hard is to 
capitalize on them and make money from them. The performance of any 
trading system should be measured with actual trading (either demo or an
 account with limited funds). 
2.
 Sometimes you lose even when you have followed your system to the 
rules. Losses are part of the game, there is no possible way to avoid 
them, and we need to learn to lose. So if you have followed your system 
100% and took a loss, celebrate it! The only way to stay ahead of the 
game is by rigorously following your system. 
3.
 Sometimes while trading large positions you can lose control of your 
emotions. Don't be overly aggressive with the market and follow a well 
planned money management technique. It should tell you what you are 
going to risk on your next trade. 
4. Try to understand why your system works, this way you will develop the required confidence in yourself and your system. 
5.
 There will always be some “indicator” that could have kept you out of a
 losing trade. But remember your system is not designed to win all your 
trades, but to win most of them. 
6.
 When you finally created your system, describe it in simple and logical
 terms. If a 15 year old kid is not able to understand it, then 
something is wrong with it. 
7.
 Use only 2-3 indicators: one indicator to identify the trend and one or
 two indicators or variables for entries and exits. The more indicators 
you use, the more complicated your system becomes. Most of the time “the
 simpler the system the better performance it will have”. Also use 
non-correlated indicators, do not choose two indicators that are 
supposed to measure the same market condition. 
8.
 Test your system over large data samples (over 50 trades) and in 
various market conditions, this way you can see under what conditions 
your system works better. 
9.
 If you decide to trade several currency pairs, try non-correlated 
pairs. For instance, if you trade long the Euro and long The Pound, your
 are likely to get the same result on both of them, elevating your risk 
if the market goes against you. 
10.
 News trading? Determine whether you are going to keep your trades open 
during important news announcements. If you are trading for the short 
term you are likely to keep tight stops, and an important news 
announcement might hit your stop loss level. 
11.
 While you are in a trade, open your mind to every possibility, 
sometimes you don't see or ignore evidence against your trade.
