Distant Between Band

[biztet]

Hi, need help with this one. How can i tell the EA to check if the distant of the 2 bands if it's increasing @ decreasing? Thanks.

Check distance over candle id's, for e.g if id4is<if3&id3<id2&ifid2<id1 then gap is increasing.

@jstap so I'll need to use lots of block?
What i understand your example is only for single band? I'm trying to get distant between 2 band in candle id3<id2<id1.

[jstap]

Yes multiple blocks, as many as you need, but when upper band is increasing, the tower is too.

@jstap I'm sorry, what i mean is the distance, gap between the 2 bands. Upper1&Upper2, Lower1&Lower2.

[jstap]

On you're picture you have an upper and lower band, they both move in conjunction.

[jstap]

Not sure what you are doing with your formula, this is an idea of how to do it, you will need as many blocks as candles:

[biez6900]

it is however simple, the upper limit returns a price the lower limit also returns a price, I subtract the 2 with a formula block to measure the distance in price

if you want to measure the evolution you do the same on x previous candle with a condition block which checks the evolution of the varialbe

[jstap]

Ok but the lines are never = so you need to set a distance value to know if lines are widening.

Thanks @jstap @biez6900.

I'm thinking like this, but don't know how to do it.
For Upper bands

value@price (above-below(id3)) < (above-below(id2)) < (above-below(id1)) = expanding

value@price (above-below(id3)) > (above-below(id2)) > (above-below(id1)) = shrinking

[jstap]

@biztet You can do it like this: https://fxdreema.com/shared/GFLkPs3xb

[biez6900]

yes jstep you are right about the answer you gave me, doing as would even be better

[biztet]

Thanks guys. Appreciate it. I'll try this. Thanks again.

Don't think you need the +2? As was, it was was comparing candle to the one before, as is now you are messing with the the distance of a candle, but you change this on different blocks..

[biez6900]

here we do not count the lower limit to the lower limit +1 but the difference between the deviation terminal 4 to the deviation terminal 2 and we look for a positive evolution, and by taking a step we avoid too weak evolution
