Well, at the cost of repeating, I was trying to sound “Simple” not “Easy” ! They both have no relationship...

The key is not to let left (investor) and right (trader) talk to each other. This is the financial meditation :-)

One simple way (to start) is to keep the two (trading and investment) instruments different. For example I invest in stocks and trade in bitcoin. [Fact: I invest in bitcoin also, but just as an example]. So you cut out the news for bitcoin and cut out market info for stocks. Don’t try to find cause-effect relationships in bitcoin (news) and don’t try to change cause-effect relationship for stocks with market movement [unless cause change don’t let the effect change]

They both are Simple in the end. Its [Chaos] Trading and [Value] Investing :-)
