I'm a newbie in regards to trading, price charts, indicators and such. I'm not even sure all the terminology I'm using it's correct, since English it's not my native language, so please go easy on me :)
My question is very specific and is about an up-trend price pattern in regards to its EMA(25) indicator.
As a starting point, this chart may be used as example for what I'm going to ask next:
The idea is this: In an up-trend pattern as the one depicted above, does it make sense to consider this EMA in particular as a dynamic support? I know that any plotted mean line is arbitrary chosen, but this one, especially in sections 1 and 2, seems to work as I was suggesting. As a consequence, every time one or more candles break through the EMA, I can imagine a (temporary?) trend inversion, thus a possible entry point. In example, exactly at the end of the plot, probably an inversion is going on; so waiting until the candles "touch" the EMA line, just before they rise again, could be seen as a good entry point. As it was during the 2 hours period marked as "A". Thanks.
Edit: It seems that here I partially found an answer.
