Ask-Bid = Variable

[samir]

Hi, how are you?

I do not dedicate myself to programming, I am very basic, and much more difficult when I have to edit things that are already done.

Current Ask price
Current Bid price

I want (Ask-Bid) = A

Next, into A in function, example:

if (A > My Imput(0))
{
blablabla
}

How to substract Ask-Bid?

Of course, it would be every tick, How is it done?

Thanks and grettings.

Hello samir,
Thanks for your post.

You can subtract Ask from Bid by using the GetCurrentAsk() and GetCurrentBid() methods, respectively. The following snippet would accomplish this and assign it to a variable "A".

private double A;
protected override void OnBarUpdate()
{
	A = GetCurrentAsk() - GetCurrentBid();
}

Please let me know if you have any questions.
