Hi,
It seems that some things are not clear enough :-)
1. If you create the formula that uses ma( v, 260 ) or sum( v, 260 ) or any other summation or averaging with period of 260
bars YOU MUST have loaded AT LEAST 261 bars of data to see ANYTHING. Otherwise the value of the sum or average
is undetermined ({EMPTY}) (for the first 260 bars)
2. If any part of the formula is undetermined IT WILL NOT generate ANY signal
3. Make sure that you have loaded at least 261 bars. The first results could appear only AFTER the bar #260.
4. If you are using "Parial loading" feature please choose File->Load remaining quotes->Current stock or use "Load remaing when selected"
option in Preferences/Miscellanous.
BTW: 20% spike over 260 bar moving average could be determined by the following formula:
buy = volume > 1.2 * ma( volume, 260 );
Hope it helps,
Tomasz Janeczko

Subject: [amibroker] arrow
Hi Tomasz and others...
This is really pissing me .....
after all that work reload ami etc ...the arrows have gone yet again itseem that they stay for a few searches then ?
but are theses more they work with some formula's but not others
even after a reboot no arrows for this formula and a few other also no arrow in guru com using the mencing missing arrow formula's...
here the offending buggar for those of you want to be driven to the edge :)
/*Volume spike2
David Holzgrefe
16/02/2001
volume average of 260 periods divided by 52 to give a weekly volume with a buy signal .
sum(v,260)/52 todays volume is greater than the volume for the past 5 periods add together
sum(v,260)/260 trading above annual average or
buy =volume > ma( volume, 260 );
*/
annvol = ma( volume, 260 );
buy = annvol;
now you do as told ok :-
hmm maybe Tomasz should but me on the pay roll as a crash test dummy
Thanks David
