The point of “support” for any currency is the price level beneath which a currency never trades – effectively its market “bottom”. Whenever the price reaches this level, it almost always bounces back upwards, and for this reason many people will invest when a currency hits that point. Conversely, the “resistance” point is the traditional high point of a currency price, above which it never trades. If you are looking to cash out, this is a good reference point.

Of course, the old saying “there’s a first time for everything” exists for a reason. There will come a time when a currency breaks its support or resistance levels, and this is seen as hugely important. When a currency does this it will be expected to continue this trend, possibly for an extended period of time. It is therefore a good time to get “in” if it is rising or “out” if it is falling.
