With today's sophisticated financial market operating worldwide, world currencies have their own distinct sets of resources for measuring their worth over time. The general forex or foreign exchange market helps to promote the comparison of different world currencies against each other and against other assets, to help individual traders and investors take advantage of conditional values for those currencies.

As their names suggest, support and resistance act as barriers within forex markets and are easily spotted on price charts either preventing price from moving higher or lower. This can be seen on any forex chart and across all time frames with those most influential areas of support and resistance potentially still existing in the market years after they were originally created.

The basis of technical analysis in forex trading is identifying recurring patterns on price charts that have a high probability of pre-empting a future price movement. Technical analysts are not necessarily interested in the fundamental aspects driving the market such as news or events.
