Let us start studying risk reward ratio using PAX data. I have removed the overall picture and just focus on the data from Feb 15, 2008 - March 24, 2008.
In determining the risk reward ratio, I first assess where my support and resistance are. The support line (labeled recovery line 1) is drawn by connecting the low of Feb 15, 2008 (2.95) and the low of March 11, 2008 (3.10) and extended to the right side of the chart. That line crossed March 17, 2008 at 3.14, which gives a nice support on the downtrending price. After hitting 3.15, the price bounce up and close at 3.20 that day and heads up on the succeding days.
Now we have identify our support, let us now assess our data and look for that level that will give us the resistance. Price retraces to its lowest at 3.70 on Feb 27, 2008 and bounce up. The 3.70 level gives a support during that retracement. When that support was broken, it reverse its role from support to resistance. We can identify the 3.70 level to give resistance to the rallying prices on its way up.
Having identified support and resistance, let us now look at our risk-reward ratio if we want to enter PAX. Closing price on March 24, 2008 is 3.45. If we don't have PAX and plan to buy the next day, March 25, 2008, we should study our chances of winning. Assuming it will open at 3.40 the next day, let us see how is our ratio if we will be buying at 3.40.
Risk is the difference between support and our planned entry price. The support line we have discussed above will be crossing at 3.18 on March 25, 2008. Entering at 3.40, our risk is 3.40-3.20 (The price based on fluctuation) which is 0.2.
Reward is the difference between resistance and our planned entry price. Subtracting 3.70 with 3.40, our estimated reward is 0.3.
Ratio is the quotient from dividing risk by reward. Our ratio therefore is 0.2/0.3 (2:3) or 0.67
Question: Is 3.40 a good entry? No because the best entry is at 1:3 ratio or 0.33. So what will you do if you want to buy PAX? Wait for an entry price that will give a ratio of 0.33 or lower. The odds should be in your favor.
