The RSI and MACD are both trend-following momentum indicators that show the relationship between two moving averages of a security’s price.

MACD

The MACD is calculated by subtracting the 26-period EMA from the 12-period EMA. The result of that calculation is the MACD line. A nine-day EMA of the MACD called the "signal line," is then plotted on top of the MACD line, which can function as a trigger for buy and sell signals. Traders may buy the security when the MACD crosses above its signal line and sell, or short, the security when the MACD crosses below the signal line.

A bearish crossover occurs when the MACD turns down and crosses below the signal line.

Relative Strength Index

The RSI aims to indicate whether a market is considered to be overbought or oversold in relation to recent price levels. The RSI calculates average price gains and losses over a given period of time; the default time period is 14 periods. RSI values are plotted on a scale from 0 to 100. Values over 70 are considered indicative of a market being overbought in relation to recent price levels, and values under 30 are indicative of a market that is oversold. On a more general level, readings above 50 are interpreted as bullish, and readings below 50 are interpreted as bearish.
