open

Opening price of the current bar

• open number|ValueWithHistory Current bar's open price with historical access

local current_open = open
local prev_open = open[1]
local open_change = open - open[1]

high

Highest price of the current bar

• high number|ValueWithHistory Current bar's high price with historical access

Usage:

local current_high = high
local prev_high = high[1]
local high_breakout = high > high[1]

low

Lowest price of the current bar

• low number|ValueWithHistory Current bar's low price with historical access

Usage:

local current_low = low
local prev_low = low[1]
local low_breakdown = low < low[1]

close

Closing price of the current bar

• close number|ValueWithHistory Current bar's close price with historical access

Usage:

local current_close = close
local prev_close = close[1]
local price_change = close - close[1]

volume

Trading volume of the current bar

• volume number|ValueWithHistory Current bar's volume with historical access

Usage:

local current_volume = volume
local prev_volume = volume[1]
local volume_spike = volume > volume[1] * 2

Price Variables - Calculated

Derived price values calculated from OHLC data

Commonly used for technical analysis and indicator calculations.

hl2

Average of high and low prices Calculated as: (high + low) / 2

• hl2 number|ValueWithHistory HL2 value with historical access

Usage:

local mid_price = hl2
local prev_mid = hl2[1]

hlc3

Average of high, low, and close prices Calculated as: (high + low + close) / 3 Also known as "typical price"

• hlc3 number|ValueWithHistory HLC3 value with historical access

Usage:

local typical_price = hlc3
local prev_typical = hlc3[1]

hlcc4

Weighted average emphasizing close price Calculated as: (high + low + close + close) / 4 Gives double weight to the closing price

• hlcc4 number: ValueWithHistory HLCC4 value with historical access

Usage:

local weighted_price = hlcc4
local prev_weighted = hlcc4[1]
