Price "near" an indicator line

[sandman55]

Hi Team

I'm working on a strategic logic where one of the conditions is the bar closing price Close[0] is "near" (price can be above/at/or below) the line of an indicator. "Near would be measured in Ticks, say within 10 ticks. For example, condition is met only if Close[0] is within X n. of ticks from say a EMA. I tried the below but it doesn't seem to work. Any thoughts on how to achieve this:

else if (State == State.DataLoaded)
{
...
EMA1 = EMA(Close, 30);
..
}

protected override void OnBarUpdate()
{
...
if (MathAbs((Close[0] * TickSize) - (EMA1[0] * TickSize)) < 10) Enterlong()
}

Any thoughts on what's the issue of if there's a better way to achieve the result I'm looking for?

Thanks!

Hello sandman55,

Thank you for the post.

The first thing I can see here is the way you are doing the tick math, generally you would use something like the following to calculate a price in ticks:

Close[0] - 10 * TickSize

That is the close minus 10 ticks. Your ema would be the same or

EMA1[0] - 10 * TickSize

You could try something like the following:

double baseEma = EMA1[0]; 
double upperBound = baseEma + 10 * TickSize;
double lowerBound = baseEma - 10 * TickSize; 

if(Close[0] >= lowerBound && Close[0] <= upperBound)
{
   // price should be between the bands now
}

I look forward to being of further assistance.
