I did too, and small mistakes and those that influenced the further course of trading and all at once do not remember,but I fundamentally agree that you must always remember the old and do not shun new knowledge! and the most important thing in all this is the knowledge about the relationship between people in the market. Remember if you were deceived once then you will be deceived a second time! Do not trust those who are enriched at the expense of the poor!
And about this post I will say that this is a very poorly veiled advertising!
