You will note on the chart I have selected the average range indicator, this displays the daily ranges as an average over any period you define. The software defaults to 20 days or roughly one trading month. I prefer to use three months or 66 trading days, as my default being 3 months of roughly 22 trading days each month.
Using this tool and measuring the value, the average range was $1.37. So, a third of this value is $0.46. That means for this strategy, I placed my stops 46 cents behind each major milestone as it was crossed. As FDX crossed the 50% point or $94.28, the stops were raised to $93.82. The following day the market opened and pushed lower, then closed near its high. The low on Nov 12 was $93.84. We were able to ride the short counter trend and then benefit from prices pushing higher.
November 15 saw the market touch the 75% milestone. Our stops were moved up to $94.89 and we would have been stopped out there on that day. You can see in this example, on one occasion the stops were wide enough to hold us in another day, only to be taken out the next. The rule of a third of the daily range allowed us to stay in the trade and return a $1.53 move in 3 trading days.
Testing how close you run your stops is an important part to your trading. Using the average range tool in the software can help identify the average range easily. As I mentioned, I use 66 days or 3 months for US equites, this is a variable you might also like to modify in your testing.
Good Trading
