When a market price comes close to the support or resistance area boundary, the trader will set up a position: long if prices are actuating lower and close to the support boundary, and short if prices are actuating higher and toward the resistance boundary. It sounds uncomplicated, but remember, trading comprises numerous surprises.
Note that the effectiveness of the support and resistance at the boundaries is commonly influenced by the number of times the market has pivoted at the boundaries. The rule is that the more times a market has reached a support or resistance boundary, and then reversed course, the more powerful is that boundary. It can also be said that the longer continues a channel, the more reliable is that channel. Therefore, a trader prefer to* determine a well-established channel or trading range for which to attempt to swing trade.
The swing trader should still apply tight protective stops. As I remarked, a breakout can occur anytime, might due to bad political news etc…Good money management strategies will keep traders away of troubles. A good area to set a protective stop is exactly outside of a support or resistance boundary that constitutes the trading channel or congestion area. For example, if a market in a trading channel is nearing the upper boundary of that channel, the swing trader would establish a short position and would prefer to place his protective buy stop just above the resistance level that serves as the upper boundary of the trading channel.
In direct contrast, if a market is coming near the lower boundary, the swing trader would establish a long position and place his protective sell stop just above the support level.
