An EMA that tries to remove its own delay.
It feeds the EMA a price corrected for the lag (price plus the change over half the period), so the line turns earlier than a normal EMA.
Worked out by the same code the builder uses, on stored daily candles. Move a setting and the line moves with it. This is what happened, not what will happen.
Entry: Price close crosses above Zero-lag EMA(21).
Less delay also means more false turns. In a choppy market it flips more often than a plain EMA.
