Resistance and Support
In trading there is biggest concept used is support and resistance. Everyone is enough to create their own idea to measure the support and resistance.

Have a look on basics.
Market move up down and the top point reached it back is resistance.
If the market continues top again then the lowest point it started back to support. That the way of resistance and support continually form oscillates as the market in over time. Reverse makes a true to the down trend.
Plotting Resistance and Support
Remember that the level of support or resistance is not correct numbers.
Lot of time you see the level of support or resistance appears to be broken, as soon as you see that market makes to testing it. Support and resistance represented as usually by the shadow candlestick.
Just notice the candles which tested the level of support of 1.4700. Those times it seems that support was breaking the market. We see that market was testing merely that level.
Really how we know the support and the resistance had broken?
No answer to that question. Support and resistance had broken as arguing that actually past close the level. If you see this is not the case.
Just see with an example what happens of actually price which is closed past 1.4700 to support level.
It has been that price closed low1.4700 support level and it ended up by rising back up.
In case you realize the breakout and sold these pair, that means you’re seriously hurt.
You got an idea that support actually not broken; still an intact and much stronger.
You must get some idea which support and resistance “zone” more than concrete figures.
Find the way of zones with help to plot a support and resistance in line more than candlestick. Reason is line only showing closing price but candlesticks are extreme up and down.
These up and down can misguiding because “knee-jerk” in often time which react in market. if someone doing something strange when asked it, they gives reply “Sorry it reflects”.
Interesting tidbits related to support and resistance:
• The price allows through resistance and could potentially it becomes support.
• Often price tests the level which resistance or it supports without breaking. Resistance or support to stronger area.
• Support and resistance level breaks strength follow through moving depends strongly have been holding by broken support and resistance.
You can spot the potential resistance and support very easy by practicing.
