Support and Resistance are not lines, but areas or zones. Mapping them is not a exact science, it is an art. Let me explain.
When you find support and resistance, you look for areas that it touches several times. The more times it touches, the stronger the support or resistance.
The red line shows one Support/Resistance area. This area was testing many times.
Another way of showing Support and Resistance areas is to use Ichimoku clouds.
The dotted area is the cloud of support and resistance. After the candles broke through the cloud, they dropped rather nicely.
