Syntax Format
tma(series, period)
Overview
TMA
(Triangular Moving Average) is aimed to smooth the price movement and show more significant trends. The main difference of this Moving Average is adding an extra averaging layer for extra smoothing of the price movement. The TMA
is suitable for long-term strategies, reducing the noise and showing prominent trends.
Parameters
Parameter | Type | Purpose |
---|---|---|
source | series | Input series, taken into calculation |
period | numeric | Moving Average period |
Returns*: series
.
*If there are less than 2period-1 values in the series – the result is nan.
Example
instrument { name = "Triangular Moving Average", short_name = "TMA", overlay = true, icon="indicators:MA" }
period = input (10, "period", input.integer, 1)
source = input (1, "source", input.string_selection, inputs.titles_overlay)
input_group {
"TMA Line",
color = input { default = "#4BFFB5", type = input.color },
width = input { default = 1, type = input.line_width}
}
local sourceSeries = inputs [source]
plot (tma (sourceSeries, period), "TMA", color, width)
Formula
The formula for calculating TMA
is:
The first value of TMA
is calculated as sma(series, period)
. Then, in order to add an extra averaging layer, another SMA is added.
