Well Here is what I did, it will will in the downloads section ... Here is the DLL file, rename the file for JWWILDER.[censored] to JWWILDER.dll Then copy it in Drive:\\PROGRAM FILES\\Equis\\MetaStock\\External Function Dlls The way this dll was programmed is that it calculates a SAR based on an data array of your choice and a limit value of your choice. I did not want to limit it to what was in the book. The syntax is: ExtFml( "JWWILDER.CSAR", Data Array, Limit Move) For example you could check the standard SAR, compare the built in indicator Parabolic SAR with a maximum .2 To the following indicator: ExtFml( "JWWILDER.CSAR", Close, .2) You will see that they are almost the same ( The difference lies in the fact the MetaStock SAR uses High and Low Values whereas the dll only uses one data array, in this case only the close value) Anyways to recreate the System with the accumulation swing index you will need to write the following formulae: For an indicator use : ExtFml( "JWWILDER.CSAR", ASwing(5), 60) { Wilders uses a 60 point Trailing stop in the book, 5 is the Limit move for the swing index, and you can replace that by any value you want } For A buy signal use: AccSwingValue:= ASwing(5); SARValue:=ExtFml( "JWWILDER.CSAR", AccSwingValue, 60); Cross(AccSwingValue, SARValue) For a sell signal use : AccSwingValue:= ASwing(5); SARValue:=ExtFml( "JWWILDER.CSAR", AccSwingValue, 60); Cross( SARValue, AccSwingValue) Hope this helps, Patrick :mrgreen:

Sorry it is in the Downloads section, right here : http://forum.equis.com/drm_main.php?mode=drm_cat_view&cat=8

[quote=JWWILDER.CSAR",RSI(14), 1) this will only have any significance if scaled in the same window as the rsi(14) indicator ... Hope this makes sense. Patrick :mrgreen:

Hi Patrick, I changed some variables related to the SAR portion and was able to get quicker signals (about 3 periods) than the standard SAR. However, like the standard SAR it doesn't appear the ExtFml SAR can be used as a trading system - good exit points though. The buy and sell formulas generated pretty good signals but were not real consistant when compared to hindsight MACD Peak/Trough signals. I need to try different variables to see if any change occurs. I am still having difficulty understanding the Accumulation Swing Index and need to further review Wilder on this. I know he used extreme points but the values I get doesn't seem to relate to the extreme points I can manually observe looking back over the data. As I posted before the ASwing is giving me a value of 2550 compared to the current NDX of arround 1580 ( the exterme point the way I figure it should be somewhere around 1628). I just have to do more research on this. Thanks, Charley OK - I see that Wilder says that the 60 points are NOT in terms of the PRICE. pp. 97 New Concepts in Techinical Trading. I now understand no relation to price. Now I can work on the variables so the sgnals are optimized for the NDX. Later, Charley

That's a 30 minute thing ... I guess I will just add this function to the next ForumDll version ... I don't see the need to have a separate dll. Maybe that will get some people to upgrade to 9.0 :twisted:

Well ... I don't know for sure, never tested it :goofy: :oops: Just tested the beta 8.0 that's in the download section right now and it works on my Meta 9.1 ... But It might be because I have all the dev kit stuff installed on my machine ... Maybe someone else should test it ... Patrick :mrgreen:

I could create the function for you if you want but I think it would be too difficult and too confusing to change the current version. Remind me about this in a few weeks if you still want it :D Patrick :mgreen:

No because the standard SAR uses high and low values ... The custom function in your case only uses the close, so it should look very similar but not exactly the same. Patrick :mrgreen:
