While discussing implied volatility and expected move you said the values shown on the right side are 1 S.D move with 95% probability. One S.D represents 68% probability. Thanks for the helpful tips and the mini sessions.

My bad. You are absolutely correct. Around 68% of values of within 1 standard deviation of the mean. 95% of values are within 2 standard deviations of the mean. Apologies for having misspoken on that one. ^Barb

Hi Barb, you mentioned looking for a tight bid/ask spread. Is there a general guideline to use for that?

[@tradertalkswebcasts]

In our example trading plans, we have been using a Bid/Ask spread of 10% or less as a guideline. There are a number of example trading plans under the Trade Management Mini Session umbrella.
