For binary options on such short trades, you can not rely on trend tracking. The time is too short, your option can drift in all directions, and most importantly, it is difficult to choose a graph with which gives you the right time scale compared to the binary option.
I explain, if you rely on a graph at 2 minutes interval, you can notice a wonderful trend. but if you choose 5 minutes, then your tendency may not look like anything anymore. the question then arises, the evolution of your binary option is part of what trend? the first, the second, another?
I advise you not to trade this kind of products if you are not experienced. Your only assets are the supports and resistances VERY CLEARLY identified (and therefore difficult to notice in most cases), combined with the use of the other known technical tools (RSI, Fibonacci, etc.). all will take you time!
good luck
