Hey W- I think this is right on the money! I got both MA's to plot exactly the same as the stock indicators, except that they start on the first bar. They plot quickly too. When I compared them side by side their counterparts in Explorer, the times to calcualte were identical. Very nice! :rockin:

In laymans terms, it says, SMA ... until the number of bars on the chart is equal to or greater than the number of bars wanted by the user, just take the average over the number of bars that exist... so on the first bar, the SMA returns the average of the first bar i.e the first bar on the second bar, the average of the first two bars on the third bar, the average of the three bars etc etc until the right number of bars is reached, then it works just like 'normal' EMA the first value is the value of the first bar, from there its just like an EMA should work -> %pct(YesterdaysMA) + %pct(TodaysValue) wabbit :D

Funnly enough, in the dll it goes like this: if(i<=1) l_fMA = l_psData->pfValue; else l_fMA = (a_psResultRec->psResultArray->pfValue[i-1] * (1.0 - l_fPct)) + (l_psData->pfValue*l_fPct); wabbit :D

... on second thoughts, if you want a copy of the dll as a TESTER then please PM me.... wabbit :D

Nah didn't fall for it... although, as I said, I did download it, on purpose. I like collecting viruses (virii?) and stuff like that. I used to have a large collection of virii, trojans and malicious stuff, before my old HD died taking out the rest of the components with a massive power spike inside the case! I had years of collected works wiped out in flash of blue light, with sparks and smoke. (I never backed these up, on purpose) Some of the code was very good, it gave me some great ideas on how to do other things more efficiently etc. Some, like this .pif file were just poorly constructed and written annoyances by some bored pre-pubescent in a high school IT class. I just like taking code apart... its sort of a hobby. Whether it be MS code, or any other code. Its also a good way to test out different hacking tools and decompilers etc. Not to mention a good way to test out some of the different anti-virus and firewall software. Download the virus onto one machine in your local network, and try to get it to infect another on the same network, through differnt AV tools and firewalls. You'd be surprised how many things can get through one, two or more of the different defence systems. Each has its strong points and weak points. e.g. Windows firewall is very little defence against even (nowadays) un-sophisitcated attacks. wabbit :D
