Dont worry, I think we will have another one in the future. But first, I would like to do some research to make it as true a random walk as possible. I would also like to use much larger histories, but this is going to take some work in picking the true histories so that they arent obvious...

Hello everyone, It is time to announce the answers for the random chart contest held this past week. (I know, I am a little later than I promised) The original thread is located here for your reference...

LOL!!! I did this on purpose! I transposed all the real data to start at 30! :) If I left the real prices it would be too easy to figure out which is which. Trust me, they are NOT all random. You will see when I give the results. I will reveal which charts are real and their exact...

dottom I dont know what brownian motion is. But this is what I do. I set up levels of probability, then set a volatility for each probability. So an open gap of 0% to 0.5% might have a 80% probability. A 0.5 to 1.5% might have a 19.9% probability, and a 1.5% to 8% gap might have a 0.10%...
