For general stress/anxiety issues:

1) Take a very deep breath for 4 seconds, hold it for 4 seconds, let it out for 4 seconds. Do this for a few minutes several times a day whenever you feel anxious. The deep breathing causes the sympathetic nervous system to relax your blood vessels, thus lowering your blood pressure (you can see for yourself on a blood pressure monitor). Do it at bedtime and you fall asleep faster, too.

2) A supplement called SAMe works very well for many people without putting them in a "fog". It is an OTC, natural supplement, but kinda pricey. Works well, though, I've used it before on ambulance runs (ex-EMT).

For trading:

1) Only take a high confidence trade.

2) Don't set your stops too tight. Remember, a trade needs to "breathe"...they seldom go straight up or straight down. A good rule of thumb I use is 3-5 times the bars of the chart you based your trade on (charts less than the Daily) and 1-3 times the bars of a Daily chart. So, if you are trading off the 30min chart, it may take 1.5-2.5hrs for the trade to mature.

3) Don't risk too much on a trade if you don't have 100% confidence in your strategy, and rather than trading that strategy, spend your time finding one you HAVE 100% confidence in.

4) Don't become greedy or try for the "homerun" every trade. You can make a good living on 10 pips per trade, just get to the point you can trade more contracts.

5) Once you are out of a trade, stop thinking about that trade; always be looking forward, because looking back in trading at the "what-ifs" won't just make you anxious, it will make you crazy!
