It all depends on how you manage your trade/investment! It amazes me that many are talking about the "edge" they have to perceived to have here on ET yet nobody talks about managing a position (let it be a short term or longer-term position) - this is a sure sign of stupid short term mentality and complete ignorance of how money is actually made in the markets! With a trend line if you buy on weakness and accumulate with wide stops and have patience you can make more money than jerking off with day trading. This assumes that the trend is strong, you caught it early enough and SMART position and money management is factored in. Why? Gap ups you can never monetarize in day trading! Scaling in is not the same as adding to losers! Most professional traders scale in. In fact, HFT bots do nothing but scale in for hours, 1-2 lot at a time, and scale-out with the same notion.
IMO NO. And to my knowledge there is no specified way of measuring the lines,AKA what classifies as trendline and what does not. As long as its not proven in strategy test its subjective imo.
Trading is an art, NOT an exact science... It is all patterns and recognition of such... Algo bots use trendlines and they use them differently from one another, so what?
Why? What do you think algo bots who run 80-percent of the volume USE? What is your idea? Fundamental analysis, tea leaves? I won't even ask for "evidence", of your assertion as it would be clearly ASSININE... Algo bots use many things as they are many, some of them most assuredly price action trading, some use even social media snooping. If you have difficulty believing this that is ok. I am not a church so what you think/believe is immaterial to me. Do you want proof? In any of this, you are funny...
So you mean you imagine algo bots use trendlines in your dream, impressive, you should have won a lot of money (in your dream too), lol xd!!!
Rest assured that market making algos or other institutional algos, you are concerned with, do not base they trading on price action.
