Hello,
I have been sent an autotrend code that is coded in Easy language. Is there someone in the group who has seen something similar in an AFL code? It might be worthwhile trying to find such a code. I have tried but haven't found one as yet. Here is the code:
{
This indicator:
(1) INSERTS DnTL's/UpTL's connecting each new SwingHi/SwingLo with the next most
recent higher/lower SwingHi/SwingLo within the last 10 SwingHi's/SwingLo's;
(2) EXTENDS each new TL to the right and SETS it's color and alert type;
(3) TRUNCATES a DnTL/UpTL on the right when the next new DnTL/UpTL is drawn (if the
History input is set to "Yes"), or BarsPast bars after it has been breached,
whichever comes first.
(4) DELETES a DnTL/UpTL when the next new DnTL/UpTL is drawn, if the History input
is set to "No".
NOTE: This indicator may not work well with low-count tick bars, such as 10-tick bars,
etc., because the time resolution of the bars may not be high enough for each bar to
have a distinct time stamp.
}
inputs:
SwHiStrength( 4 ),
SwLoStrength( 4 ),
BarsPast( 10 ),
History( "Yes" ),
DnTLColor( Red ),
UpTLColor( Cyan ),
AlertType( "IntraBar" ) ;
