How does he do this (MQL 4 Question)

Check out this code.

How does this guy get those circles at the low and high of each bar?

Hi,

You wanna know how the circles are drawn or how their position is calculated?

What guy?

LOL
I assume he's talking about the guy who put in the arrows.

And the answer is: fractals and the use of buffer for graphics.

i want to know how he puts in the circles. i know it is not an object. could you please show me the snippet of code ? is the circle a custom graphic?

As much as I understand it, he's using pieces of the ObjectSet function to change his arrows depending on the situation (smart bloke), so an example snippet would look like this:

ObjectSet(Rem,OBJPROP_ARROWCODE,251);

You could also write it out as this way if you wanted to (for a more static indicator) at the buffer definition stage:

SetIndexStyle(5,DRAW_ARROW,4);
SetIndexArrow(5,251);
SetIndexBuffer(5, Signal);

I know that may seem a bit vague, but SetIndexArrow is where you define what style of arrow you want drawn. MT4 has tons and tons of them, you just have to experiment and find the cool looking ones .

cool thanks! here is a list of arrow styles
