Hi Allen, Re: Frequency of AIM updates....................
If one were doing AIM with a #2 pencil and paper, then the tedium would probably never have one updating more often than monthly. After all, if all one is doing is filling up 13 column paper with no buy or sell market orders, then it gets to have very little meaning.
Having software that gives us the "next Buy" and "next Sell" prices allows us to update only when needed even if we are doing our record keeping with pencil and paper. After all, if we already know there will be no trade market orders given for the current price, why fill out the 13 column paper?
When I've modeled AIM in Excel in the past (and Lotus 123 in the distant past) I usually did the modeling based upon monthly updates. No particular reason. I have modeled some on a bi-weekly basis, but not as often.
The Newport software is set up for weekly price additions regardless of trade activity. That is strictly for the graph function to give it the necessary data. It also helps us to stay tuned into our investments.
