Simple_cum_strategy_asset_relative_returns = np.exp(simple_cum_strategy_asset_log_returns) - 1 The Exponential Moving Average is just like it’s name says - it’s exponential, weighting the most recent prices more than the less recent prices. # Transform the cumulative log returns to relative returns The Exponential Moving Average (EMA) is a specific type of moving average that points towards the importance of the most recent data and information from the market. Simple_cum_strategy_asset_log_returns = simple_strategy_asset_log_returns.cumsum() # Get the cumulative log-returns per asset Therefore, EMAs are lag indicators that don’t predict future prices but showcase the trend that the stock price is following. Simple_strategy_asset_log_returns = simple_weights_matrix * asset_log_returns The exponential moving average (EMA meaning) is a technical indicator that determines the direction in which the price of a security is moving based on past prices.
# Get the buy-and-hold strategy log returns per asset Simple_weights_matrix = pd.DataFrame(1/3, index = data.index, columns=lumns) # Define the weights matrix for the simple buy-and-hold strategy It is most useful as an indicator where short-term price movement is more relevant. This average was developed to avoid the inevitable issue of lag that traders. It is most useful as a long-term indicator. The triple exponential moving average is a modified moving average that was created in the mid-1990s by Patrick Mulloy. To start using the 200 EMA select 200 under the period and Exponential under the MA Method boxes. Once you have done this a box will open up on your chart and you will be presented with some options. Golden Cross: The golden cross is a bullish breakout pattern formed from a crossover involving a securitys short-term moving average (such as the 15-day moving average) breaking above its long. To get all the strategy log-returns for all days, one needs simply to multiply the strategy positions with the asset log-returns. Both have their own strengths and can be used alongside other technical indicators to give traders a clearer picture.

For a SMA moving average calculated using $M$ days, the lag is roughly $\frac$. However, this comes at a cost: SMA timeseries lag the original price timeseries, which means that changes in the trend are only seen with a delay (lag) of $L$ days. It is straightforward to observe that SMA timeseries are much less noisy than the original price timeseries.
