I found a curious problem with this technique. It is a problem with the way MT4 resize the screen to be able to display the whole chart.
I entered a trade on EU and GU based on the 20, 40 and 60 pip spread. But I notice that the “pips per pixel” on EU was a lot smaller than on GU, about 0.05 on EU to 0.11 on GU.
That means that for EU, one GU pixel is about 2 EU pixels.
So I think it is important that when you see a spread of 20 pips look to see if the pixel size on both charts are similar. If not, then better use the bigger pixel size instead of smaller one.
And this triggers a question to [B]Kelton[/B].
May I ask you if you look for the 20/40/60 pip spread on EU, on GU or in both charts, to decide entering a trade?
I see you place EU in front of GU, so if you measure there, you are measuring EU pips. If you invert the order, the you will be measuring GU pips, and if you try both, you are measuring on EU and GU. If both of them have similar spread, then I think they are valid, but I don’t know if I’m right ![:slight_smile: :slight_smile:](https://forums.babypips.com/images/emoji/twitter/slight_smile.png?v=5)
By the way, I think this technique will not be a problem if you are using very high screen resolution, maybe about 1600 pixels width or more. But with 1280 / 2 that I use, the resizing is more frequent.
But if the pair is uncorrelated for long time, more minutes than your screen resolution, the similarity of the pixel size on both pairs is going to change also.
