Highest of n. bars

[percma]

Hi

I'm not sure if (pls remember i'm using Strategy Builder not coding myself) I have this condition:

Low 0 bars ago, cross below, look back period 1, Donchian Channel 1 bar 1 lower

I would receive a signal when the Low of this bar cross the lower limit of the Dochian channel set 1 bar ago (for what ever period I set the Donchian Channel).

----

On the same topic, If I use

Low 0 bars ago, cross below, look back period 1, Low 'n' bars ago

the n bars ago would mean that the Prices is compared to ALL the prices included in the period from now till 'n'? or just the price of now vs THE (only) price that did happen at the close of 'n' bars ago?

many thanks as usual

Hello percma,

Thank you for your note.

The n you pass to Low, for example Low[n], would be assigned an int number, for example 10. So, Low[n] would mean Low[10] or the low 10 bars ago, not everything between.

If Low[n] was within a loop, then you could loop through everything inbetween. You could see the following post for an example of using a while loop which adds each high to a running total, highValue.

Thank you for your reply.
It means I won't be able to loop through everything in between using the Strategy Builder?

You will not be able to do so. That is the abiding weakness of all code generators: they can only generate that which the developer precodes into them.

but if I use a Donchian channel like this?

Low 0 bars ago, cross below, look back period 1, Donchian Channel (n period) bar 1 ago lower

...i'm trying to get a signal is the price now (0 bars ago), cross below the lower level of the Donchian channel as it was 1 bar ago. (since now the lower band would be the one set by the price now).

Hello percma,

Rather than using cross below, you could check if the low of the current bar is above Donchian 1 bar ago, and the low 1 bar ago was above the Donchian of that bar, which would translate into a cross.

I attached a screen shot of how you could set this up.
