Re: [amibroker] How to find the second lowest Low of the donchian channel ?

["Steve Dugas" <sjdugas@xxxxxxxxxxx>]

Hi Thomas - Here is something off the top of my head. It plots OK but I have 
not verified that returned values are correct.

Steve

Array = Low;

Periods = 20;

LowestLowValue = LLV( Ref( Array, -1 ), Periods );

SecondLowestLowValue = 1000000;

for ( i = Periods; i > 0; i-- )

{

ShiftedArray = Ref( Array, -i );

SecondLowestLowValue = IIf( ShiftedArray > LowestLowValue AND ShiftedArray < 
SecondLowestLowValue, ShiftedArray, SecondLowestLowValue );

}

Plot( LowestLowValue, "LLV", colorRed, styleLine );

Plot( SecondLowestLowValue, "2ndLLV", colorBlue, styleLine );

Hello Bill,

thanks for your help.
I have tried a similar way but the problem is that it would detect it always
when a new low is detected.
I need to know the at every bar in the chart the 2nd lowest low. Yesterday I
thought that I know the solution,
but I have seen now that it isn't correct.
Can anyone help ?

If I understand - see if this produces what you want:

2ndchannellowback = valuewhen(ref(lowerchannelline, -1) < lowerchannelline,
ref(lowerchannelline), -1), 2);
