The advice I've seen a few times is to setup a trade with targets, stop loss before hand. Orders that are filled or not based on the market not your feeling at that moment. If price comes into a good area it might turn around often sentiment and movement in price indicates it will go further down. However a longer term time frame with over ride the price action on just 5 minute bars, that repeatable phenomena in the market is tradable so long as you are correct on the long term.
I was amazed on that 200 week moving average as that is so long term, I did not think anything like that was in play or notable in reaction. 200 day is definitely followed by many, its still gradually turning round - July 19th is the 200th day of the year and perhaps most relevant to framing this action is YTD chart. When we get that far most of the action will be positive and I think the 200 day average and 40 week turns upward
This correction should come soon
I dont really call it a correction unless its more then buy the dip. Usually takes some belief that its doomed despite being essentially a short term move, a china ban or whatever
