Oh and also - I'm not at all certain what is the difference between the 'swing points' you mention and the resulting trend line plotted from them (maybe when I read the above link you mentioned it will clarify this).......
But I have proved to myself over and over again I can draw a line on a chart that the market price will have a decisive reaction to hours or days later. I can't necessarily predict what the actual reaction will be (yet?) though i do try to look for entry points, but price does almost always react noticeably at that pre-drawn trend line
So from this observation is it reasonable to take some satisfaction from the fact I am learning to draw them correctly?
And from what you say... that would be a very good ability to aquire?
Price movement is in the market. Whatever lines or patterns you may draw or indicators you may apply are in your head. It is illogical to believe that millions of traders all over the world are going to reverse price at something you've drawn and which they know nothing about. Any movement at your line will be purely coincidental. This is not to say that your lines can't be useful, but you are making illogical and incorrect assumptions about the information they provide.
There are several cognitive biases going on here, chief among them Confirmation Bias. Guard against them.
