Buy the triple top break-out

This is where a company's share price breaks through a resistance level at the third time of asking. It can be the prelude to a strong upmove, especially if the price is not hugely over-bought on its relative strength index (RSI). The RSI was developed by J Welles Wilder in the 1970s and is a momentum oscillator, measuring the velocity and magnitude of directional price movements. Momentum is the rate of the rise or fall in price. The RSI computes momentum as the ratio of higher closes to lower closes: shares which have had more, or stronger positive changes have a higher RSI than those which have had more or stronger negative changes. Generally speaking, a share is in overbought territory when the RSI is above 70 and oversold when it is below 30.
