Most traders do not really know if they should be long or short a certain currency pair.
They have as many reasons to go long as to take a trade in the opposite direction.
Some may think that a certain target is surely going to be hit but price is moving in the other direction.
To put the probabilities on the side of the hard working trader there needs to be certainty and no doubt.
A chart may also provide analysis paralysis if to many indicators are used.
On this chart the upper arrows serve the purpose if in the instant a short or long position should be active.
And one or two indicators might be all that is needed to avoid confusion and improve on certainty to take a trade in the right direction of price.
