You enter a search query; for example you may enter Vaio Laptop or Omega Watch; then you may click on the  Search & Calc  button.

This is what happens.

1. bidmaxCalc launches a robot to fetch the relevant information from the WWW space
2. bidmaxCalc collects a sample of relevant eBay items
3. once the data is collected bidmaxCalc proceeds with the statistical analysis of the data
4. bidmaxCalc displays 3 categories of statistical information:

   SAMPLE

   • sample size: this is the size of the eBay items collected sample
   • major categories: this is the number of eBay categories that are the most relevant to your query. bidmaxCalc retains only the sub sample related to the top eBay category and display the statistics relevant to this category. This category is displayed in the banner area at the top of bidmaxCalc display panel window under the search box. If the top category is not relevant to what you are looking for you may have to reformulate your search
   • supply/demand: this is the ratio of the total bidded items over the total listed items for this category. This ratio provides you with an idea oh how the situation for the product is. A ratio that is greater than one indicates that the supply is greater than the demand and therefore it's a buyer market. On the other hand if the ratio is less than one this indicates that it's a seller market. Roughly for instance the ratio reads 3.2 this means that there are one item out of 3 being bidded on
   • correlation: this is a calculated statistics which indicates the rate at which bidded prices are related to the number of bids across the eBay category. Don't forget that bidded prices for one particular item increase for every bid so for one particular item the correlation is always positive. Now this correlation is calculated for all items in the eBay category and hence will give you an idea of the bidding situation. This is an indication of the willingness to bid for a particular category. A negative correlation will indicate that the bidding is not quite engaging

   BID

   • # bids: this is the total number of bids for this eBay item category. Each eBay item which is part of the sample is collected in a state reflected by the number of bids for instance item 1 has 3 bids, item 2 has 4 bids, item 3 has 16 bids, etc. then this is the total of all bids to be distinguished from the number of bidders. In our example item 3 has 16 bids which may emanate from at least 2 bidders or more
   • lowest: self evident; this is the lowest bid price achieved for this eBay category
   • highest: self evident; this is the highest bid price achieved for this eBay category
   • average: self evident; this is the average bidding price for this eBay category. It's the sum of all item bid prices reached when the sample was collected over the number of items
   • median: this is the bid price for which half of the sampled item prices fall under or over
   • xcepts: this is the number of outliers or abnormally very high bid prices. These outliers are detected based on a multiple of the standard deviation

   BIN

   • # bins: unlike the number of bids this is the count for all BIN (Buy-It-Now)buyers
   • lowest: self evident; this is the lowest BIN price achieved for this eBay category
   • highest: self evident; this is the highest BIN price achieved for this eBay category
   • average: self evident; this is the average BIN price for this eBay category. It's the sum of all item BIN prices collected over the number of items
   • median: this is the BIN price for which half of the sampled item prices fall under or over
   • xcepts: this is the number of outliers or abnormally very high BIN prices. These outliers are detected based on a multiple of the standard deviation

The rest of the operations are similar to a calculator. Every time bidmaxCalc performs a search and calculation it stores the results as current results into a file in the folder called bxcalcache in the install directory in this directory: (./bxcalcache/etc) in file memory.bin. bidmaxCalc allows you to keep track or 128 different search and calculation results. This is what you could do with bidmaxCalc. Check the Main Options on top of bidmaxCalc windows.

• Keep: the current results in memory. bidmaxCalc will store each set of results into a memory cell and will assign to the cell a unique ID
• Recall any memory cell. bidmaxCalc will simply assign the recalled memory cell to be the current one. You may choose to recall the last results or you may pick a memory cell from the list of all memory cells
• Clear any memory cell or all of them. To clear some memory cell you may select them from a pick list
• Graph click this option every time you want to display the frequency graph that resulted from the search & calculation. bidmaxCalc will display the graph using the default Internet browser on your machine.
