Clever, but not very accurate with most collectors items!
I am being very negative I know, but I feel your programme will only work effectively with really large numbers of similar products.
It depends entirely on sample size.
I would imagine that most collector's interests are like mine, highly specific and only a limited quantity are sold each month. If for example the sample size is 7 (Query Adox cameras) then it picks Saturday as the best day to sell this camera, simply because that example sold for the highest amount.
I don't think that represents real life - Tuesday had the highest number of bidders which I think is the real test of the efficacy of the forecast.
In other words price is only one indicator - I think that number of bidders is also a vital statistic.
Don't get me wrong, its a brave effort, but I simply think there are too many variables in the collectors market to be able to forecast accurately.
My advice to my Jeweller client who wants to start selling sell hand made gold & silver jewellery has been simply ignore times & days, make certain that your layout attracts the customers to your jewellery, so I am not certain your programme will work for more standardised products either.
Am I being too hard on this venture? It is an original concept after all.
Oh yes, as Mrs M & Puppy Raiser are abed and Lexie has travelled to unknown parts of the world (usa pronounced oosa, sounds like somewhere in Japan!) BJ is poorly and Region2 has told me he is very busy, so on behalf of everybody may I formally welcome you to the forum. (We Brits are a bit more formal, the others would have just said say Hi! Welcome!)
