  • Petra on Programming: Truncated Indicators [Financial Hacker]

    Cumulative indicators, such as the EMA or MACD, are affected not only by previous candles, but by a theoretically infinite history of candles. This makes them return slightly different results depending on the tested period. Although this effect is often assumed negligible, John Ehlers demonstrated in his July S&C article that it is not so.
