Hi Gang, In checking my spreadsheet version of the online calculator I found an error that I fixed the way I thought it needed to be, but it turned out that the sell price was a match but the buy price did not match. I scratched my head for quite a while but never found out exactly what I did differently that made the difference. Then I did the calculations where the sell and buy would happen relative to the current price and I found an oddity with the online line calculator.

PC 3498, 377 shares, share price $9.28, buy,sell, % shares all 10%. The Online Calculator comes up with:

 @ Stock Value Above $4373 
 Min Sell Order Size $437 
 Min Sell Price $11.6 
 Min # Shares Sell 37.7 
  
 @ Stock Value Below $2915 
 Min Buy Order Size $292 
 Max Buy Price $7.73 
 Min # Shares Buy 37.7

The percentage between current price, and the next sell, 11.6/9.28=125%. The percentage between current price and the next buy price, 9.28/7.73=120% going up or 7.73/9.28=83.3% going down.

With my spreadsheet version I get the same next sell price, $11.60 but the next buy I get is $7.56. Calculating the percentage difference between the current price and the next buy percentage is 9.28/7.56=122.75% going up or 7.56/9.28=81.46% going down.

I can not seem to get the same percentage for the buy as for the sell but I am a bit closer. This is good as it delays a buy a bit more, which is good.

I am contemplating making the the next buy at 75%, thereby matching the range on the buy side with the range on the sell side, which is quite easy to do. What do you think of this idea?

Best,

Allen
