There are Brazil stocks currently on the upswing. Here we see tangent slope changes from negative to positive on wave A or B while they are below zero. Wave C remains above zero regardless of slope tangent. This configuration offers buy on the dip trading opportunities where reward to risk is maximized. This always works for those who find themselves frequently buying at the top only to have the chart go down. This is due to a certainly valid preference for charts to show they are in a good trend before buying, but it may be mistakenly applied looking too near term. Considering waves A, B, and C together as shown will prevent buying at the top of an uptrend (or end of the uptrend), and instead enable buying at the bottom of the uptrend in progress. Note that these instances frequently appear when the price is seperating away from the lower bollinger band.
