Very interesting Antonio. You are a pure MP trader
I trade without a mp chart but use the concept of market profile into my trading.
The way you derive your key levels are very similar to the way I get mine as well. I really think trading with MP and price levels is one of the best methods of trading. The information and analysis is pure.
By the way, I noticed that chart is from Tradestation. What indicator is that? It is a commercial hack or is it located in the TS forums? I may want to take a look at it.
