Hi

I stumbled upon this indicator and its based on an ATR adjusted Renko. Id really like to know the math behind it? How it readjusts the Renko Bar Size to the ATR Value?

Its just that Ive completely forgotten where I found it. So I cant check.

My question is? Can someone have a look at the code and maybe figure out the math for it?

Thanks and regards /Bo

Cool. Thanks for the input. Im learning slowly

/danerius

I think the technical phrase is Slippage

I want to check broker slippage...

Hi fx

My goal is to make sure my EAs are working as intended. Im suspecting that some of the issues Im having are broker/platform related. So Im trying out tried and tested EAs to confirm that

The main thing that bugs me is that trades arent executed when the EA indicates it. So Im looking for an EA that is spot on timewise ie. not lagging or repainting

Wich one should I try? MA Crossover?

Thanks /danerius

Hi

I did another try and added the indicator as the EA was running. And indeed it repaints... quite a lot...

Im trying to check that positions are placed properly

Any other - more solid EA I can test that with?

Thanks /danerius

Hi

Just to check to my EAs are working as they should. I tried a standard EA from the examples on fxdreema. Its not working as it should.

Its supposed to place trades at Arrows. Sometimes it does. Sometimes it doesnt

Is this a thing or is my Metatrader setup at fault?

Thanks /danerius

Hi rafaelgrecco

THanks. Thats an excellent start for my experimenting

/danerius

Thanks fx

I just a made a surpricing discovery

High + Low / 2 is called a Median Price and a lot of Indicators have it as standard. It was a bit simpler than I thought

/danerius

A clarification...

Since theres no response yet. I thought I might explain a bit better

The principle goes like this illustration says.

Im not sure how do to do the math in fxdreema. Ive highlighted in Green the parts Im having trouble with

Thanks and regards /danerius
