effect or rounding on indicator performance and calculation

[traderfolife777]

Hello All,

I am using method- rounding to get values I can easily compare across multiple elements of my indicator . what is the effect of rounding on an indicator. I noticed some of my moving average lines are not as smooth when using rounding.

Regards,
George

Hi traderfolife777,

Rounding can cause jaggedness because there are not as many smaller increments of values in the indicator.

Rounding rounds the price. It doesn't change anything else. But by rounding the smaller increments that make the line smoother are removed.

Rounding

so if I have a condition in which I need 2 values to be exact. how do I do that considering values in indicator have many decimals. Example.4042.567986.. what are my options to get .. EMA 20 equal VWMA 14. then action is to color a region.

Hi traderfolife777,

You can round values in your conditions if that is what is needed for your logic that calls the indicators.

However, you would not need to round the indicator values in the indicator code..

You do not need to round here. You would check for the VWMA crossing the EMA to color a region. You can use two different colors, when it crosses above from below, and when it crosses below from above.

The first condition would be

if(VWMA(14)[0] > EMA(20)[0] && VWMA(14)[1] <= EMA(20)[1])

the second condition would be set up accordingly.

You should never check doubles for equality. This is not possible.

Theoretically, you could round any value to the full tick, but this more complex than the solution shown above.
