//In "Using Implied Volatility And Volume," Scott Castleman presents an interesting trading system that blends option volatility index movement with price AND Volume data to produce more reliable signals. 

//Implementing such a system is relatively easy in Afl, the language for AmiBroker. Listing 1 shows the code that should be entered in the Automatic Analysis formula window. We use the "Foreign" function to reference other symbols' data. Various data vendors use different symbols for indices. for example, "!VIX" is a symbol used by the QuotesPlus database for SP100 implied volatility, while Yahoo! Finance uses "^VIX." You may need to adjust the code according to the symbol used by your data vendor.

/*THE TRUTH ABOUT VOLATILITY - Feb2005 S&C

In "The Truth About Volatility," Jim Berg presents how to use several well-known volatility measures 
such as average True range (ATR) to calculate entry, trailing stop, AND profit-taking levels. 
Implementing techniques presented in the article is very simple using the AmiBroker Formula Language (Afl), 
AND takes just a few lines of code.

Listing 1 shows the formula that the plots color-coded price chart, trailing stop, AND profit-taking lines, 
as well as a colored ribbon showing volatility-based entry AND exit signals. The relative strength 
index (RSI) used by Berg is a built-in indicator in AmiBroker, so no additional code is necessary.

/* Multiline Stochastic 

This was recommendeed by Judith in post 45268 
Use a multiple line STOCH with the SK set on 3 and SD set on 1 
Plot periods  2,5,8,12,17,20,27 and 37. 
Plot 2 and 37 in red as borders with 2 solid and 37 dashed. These are my fences.

When all of these lines converge below 20 or above 80, I bet the farm. This has
been successful for me because I usually have the configuration the day before a
shift in direction and it lasts anywhere from 3 to 30 days. But the movement is
very noticeable and highly dependable. I've poured over charts in it for some 6
months but now I have something that works for me.

If it is a premature or immature breakout/fakeout, the 2 runs ahead of the group
and I know better than to follow it. 

Sometimes, in the sideways ups and downs, the 37 will remain behind the others.
That tells me the movement is way too choppy for my tastes -- gets into day
trading in my mind, rightly or wrongly.

When the lines are all over the place, like a bowl of spaghetti, don't waste any
time on it. Go to the next chart.
