TradingView wouldn't let me be great. The title is supposed to say, "How I Idnetify Key Trading Levels | Multi-Time Frame Semi Analysis". :)
Now that we've gotten that out of the way...I put together a quick video showing how I mark up my charts on each Friday, Saturday, or Sunday.
I start from the top down and identify the obvious high and low point...
With the Pound reaching new highs since Brexit it was clear that eventually it will run out of steam. Bang on a trend line we saw a rejection followed by a spinning top, with a strong candle close after the next 4 hours it was clear the sellers were jumping in. Easy 177 pip trade!
