This video takes a look at a possible setup developing in the US Stock market: what could potentially be the first pullback following at attempted trend change. (You could trade S&P 500 futures, SPY, IWM, etc. Similar patterns exist in most European indexes, but not Asia.) This is not a prediction or warning of any kind of crash, but just an example of how a simple technical pattern can help to read the message of supply and demand as it unfolds in the market.
(Also, here is a little more information on pullbacks in general, and check this post for more information on why entry triggers are useful when trading a pattern like this.)
