A very common and very serious mistake, which I must admit that I made in my beginnings, is to adjust the Stop Loss to the size of the position and the risk I am willing to assume.
Example: I am willing to lose $ 100. I determine that each point that moves the price is worth $ 10,
therefore my Stop I put it to 10 points of the entrance. I have not put it there because it is the right place that the previous analysis has indicated to me. In these cases, what happens is that the price touches your
Stop 9 out of 10 times, even if your analysis is correct and you are in the right direction.
It is psychology rather than technique.
Another example to finish: with respect to the previous one, if you know that the stop will be flown 90% of the time, understand that the Market Maker seeks to liquidate "high leverages", and hunt stops, that is why your stop has to be related with your entry more than everything in the wick and adjust it to a price that is far away, so that if your trade goes wrong it will be really invalidated and not hunted by the creators of the market.
