Hi, I'm still practicing with QS Language...

What if I would like to set a variable with the highest high (or lowest low) of a given number of bars?

Thanks to anyone who will answer this!

Hi,

To do so, use the "hhv" (highest) or "llv" (lowest).

Examples:

=> 5-bar highest high
a = hhv(high, 5);

=> Stock reached 10-bar lowest low
a = (low == llv(low, 10));

Hi, I have a related question
I want to calculate the Highest, lowest low value
a=LLV(Low,3);//being the lowest low for the last 3 bars
I want to use this as a sell criteria. A trailing stop of the lower donchian channel as it were
sell = close<highest LLV(Low,3)

my buy is similar, but since the last sell criteria
so my buy would be close>lowest, HHV

I'm thinking of highest since sell, or highest since buy, but we get into a loop with buy and sell as they are both dependent
hope im making myself clear

The lower Donchian channel should be:
LLV(ref(low, 1), 20) // assuming 20 bar period

So your sell rule should be:
sell = close < LLV(ref(low, 1), 20);
// Ref reference a previous bar or you can use low[1]

Plot these on a chart to have a visual confirmation
