It is often said that devils is in the details, to a certain extent I agree.
When I first encountered using trend line, I would like to compress my chart and attempt to draw the trend line touching the highest point to the lowest point as possible. Nothing wrong with that , I thought. But in between the current price to touching that bearish/bullish trend line can be a few hundreds to a thousand pips profits that are missed because I did not draw an additional line to supplement it.
The dotted line is the inner bearish trend line here in this Natural Gas chart.
Of course, had you use the day chart and draw one diagonal line, then you would still be waiting for the breakout. Nothing wrong with that because you are following the trend rules.
However, if you dwell deeper into the hourly chart, then that is where the opportunities lies. There are more than 1 breakouts before it reach the day trend line. And it is inside the forest where one can separate the different types of trees and shrubs and gather the fruits of the trees.
How broad based you want the trend line to be is up to you. You can plot it on monthly or weekly which means your time frame is very long and you may enter/exit very infrequently and need not watch the chart at all for weeks since the candles that takes to form is still in the process of forming.
Find a time frame that suits your lifestyle not the other way round. It is better to make lesser money but more frequently and consistently than to get overly stressed up with the precise entry and exit. This way, whether you win or lose, you can accept it better as your losses are not that huge that you can't sleep at night.
Peace , harmony and fun is important to me in trading. Once it gets too tense, it takes the fun out of the game. Is that the same for you ?
