Staying with trend means following the swings. If price is rising the swings will be rising so we only want long trades, when price falls with swings making higher highs and higher lows it is retracing offering an opportunity to enter long or increase ones position. Stops are always the previous swing low as we do not expect them to be crossed by price.
Alternatively if the swings are falling, lower highs and lower lows then we only want short trades, prices rising when the swings are falling means it is retracing and an opportunity to enter short or increase ones position.
With swings that are falling the stop loss is moved down to the previous swing high with each new low and high made, therefore if price should rise past the swing high it will close the trade and it should leave a profit. Likewise if the swings are falling the stop loss is placed at the previous swing low and moved up with each new high and low made, so if price should fall past the swing low again it will close the trade and leave a profit.
This method works on all time frames. The hardest part of this method is not to be tempted by the retraces and to trade the swings with no gray area. Therefore if price moves against our trend and crosses above or below making a higher high or a lower low - then we have to anticipate that direction is changing. It is not fail safe but works fairly well. One can day trade the swings or take the trade on as a longer term play. I did not include zones - I think letting the swings determine target is sufficient.
