Decimal EMA
Imagine you want a moving average line, but you want its "length" or "period" to be super precise, like 2.7 days instead of just 2 days or 3 days.
This script lets you do that. Here's the simple idea:
You Pick a Decimal Number: In the settings, you can type in a period with a decimal, say, 2.7.
The Script Does a Smart Blend:
It first calculates two regular EMAs: one for the whole number below your choice (EMA for 2 days) and one for the whole number above (EMA for 3 days).
Then, it cleverly mixes these two EMA lines. Since 2.7 is closer to 3 than to 2, it takes more from the "3-day EMA" and a bit less from the "2-day EMA." (Specifically, it takes 70% from the 3-day EMA and 30% from the 2-day EMA).
You Get a Decimal EMA Line: The result is a new EMA line that acts as if its period was exactly 2.7. This line is drawn on your chart.
Why do this?
It allows for very fine-tuned adjustments to how responsive your moving average is, giving a smoother change if you're testing slightly different period lengths.
In Short:
This script calculates an EMA for a period like "2.7" by intelligently blending the results of an EMA for "2" and an EMA for "3".
