A reversal is a change in the price direction of an asset. A reversal can occur to the upside or downside. Following an uptrend, a reversal would be to the downside. Following a downtrend, a reversal would be to the upside. Reversals are based on overall price direction and are not typically based on one or two periods/bars on a chart. Certain indicators, such a moving average, oscillator, or channel, may help in isolating trends as well as spotting reversals. Reversals may be compared with breakouts.
