I have and interesting observation and was curious if you would care to comment. I have been calculating out probabilities a lot lately and have noticed something... When there is a high probability of a certain event happening... Eg, like when we touched new highs today. I calculated out the probability of a reversal dip toward this weekend being around 90% from those new highs. That created a certainty that professionals would analyze the probability and pare back positions through today in fear of the odds probability and shorting in anticipation of it. The only sure certainty is peoples reactions to the probability. This is why I always like trading off highs/lows at key levels. There is always a certainty of people buying/selling because of the high probability of the market pulling back from those prices. In essence... A uncertain probability creates a new event of certainty!!!
