Learn for yourselves before thanking the guy.
screaming eagle said:You could simply rebut mmm...shiney and wrcmad by presenting the time range you used and the subsequent calculations that you performed to come up with the assertion that the 5% price movement was greater than 1 SD.
screaming eagle said:Miloman, I'm quite comfortable in my knowledge of statistics and also quite comfortable thanking wrcmad for his post. I greatly respect your knowledge when it comes to grading coins and about a number of other topics, however I appreciate the methodology that wrcmad presents when looking to calculate the SD of daily price moves, as I believe it to be 100% correct in accordance with the knowledge that I have on the subject, whilst being presented in simple terms. You could simply rebut mmm...shiney and wrcmad by presenting the time range you used and the subsequent calculations that you performed to come up with the assertion that the 5% price movement was greater than 1 SD. That's all I have to say on the matter.
You are reading it correctly, but your chart is not a daily.SilverPete said:Just trying to understand this (if I'm wrong, tell me). If I choose the recommended defaults for Bollinger Bands on the interactive silver chart here: http://www.investing.com/commodities/silver-streaming-chart
...then it looks like there was more than 1 standard deviation on the day in question (this is USD), or am I reading it incorrectly?

You are correct. BB 20,2 is 2 SD, not one.Miloman said:SP, one more thing 20,2 is 2 S.D. per side not 1.
Miloman said:Ok here's a little Maths that everyone can use simply, to find the sd of an acceptable 20 day BB with 1 SD, simple subtract the upper band number from the mean or the lower number from the mean. Bring up a chart and enter a 20 day moving average and 1 standard deviation then bring up a chart, you'll find on the top left 20,1,0 next to that you'll see 3 prices, one for the lower sd (lowest price), the middle price is the mean of the last 20 day and the highest number is the upper sd.
