Question about Forex Trading Journals

In some of the most viewed trading journals, people post graphs after the fact with a lot of colored squiggly lines. I am assuming that the dotted and squiggly lines are indicators although they are not labelled. There is no real mention of an entry or an exit. There is also no mention of the lot size. I have tried asking questions to the thread starters for some explanations, but to no avail. They tell you to read the entire thread. One should not have to read the entire thread to understand a post. People always attack you if you question their methods.

Could somebody explain those charts and graphs to me?
