I have now simplified my EXCEL spreadsheet sufficiently to load it into google docs .

see:

https://spreadsheets.google.com/ccc?key ... 7KAL#gid=0the way to read the spread sheet is :

Columns a to d contain 2010 data columns f to i contain 2011 data. Other columns as annotated.

The Bins columns specify the AVTR offset from the median, the median was estimated at -0.39 AVTR below the close

The probability sum column gives the probability that the stoploss is hit, since it is the sum of all the probabilities that tomorrows low is less than the stoploss.

The 2010 data was used to optimise the figures, and so to check the system works, the same figures are used on the 2011 data, the errors seem quite reasonable. However since I have only tested on one "out of range" sample this could be just down to luck.

I realised I made a typo on my last post which was kind of important since I left out a minus sign!!

it should read:

My probability data shows that the probability of hitting a stop loss set (

-0.39 + K) AVTR(25) for three values of k is as follows:

K= -0.16 Probability 33%

K=-0.24 Probabilty 24%

K= -0.4 Probabilty 12.5%

Just to clarify what these final results would mean,

Set the stoploss (0.39+0.16) i.e.0.55 Avtr below close gives 33% chance of being hit the next day

Set the Stoploss at (0.39+0.24) i.e 0.63 Avtr below close gives 24% chance of being hit the next day

Set the Stoploss at (0.39+0.4) i.e 0.79 Avtr below close gives 12.5% chance of being hit the next day

Set the Stoploss at (0.39+0.96) i.e 1.35 Avtr below close gives 1% chance of being hit the next day

These values for the stoploss will seem fairly low, this is because I am only checking if the stop loss is hit tomorrow, nothing is said about the future.

All data is FTSE350 stocks EOD data from Yahoo. For real TA nerds, the AVTR function I am using doesn't use the Welles Wilder average calculation, just a plain simple Moving average.
