hinton_map█ HINTON MAP
This library provides functions to create and display a Hinton Map visualization. A Hinton map uses squares to represent the magnitude and direction of values in a matrix. This library allows you to display multiple ticker/timeframe/indicator combinations on a single chart, using color/boxsize/bnordersize to represent the values used. The values must be from -1.0 to 1.0 in value. 3 different values can be input per square.
Example Usage:
The example below demonstrates how to create a Hinton Map for two symbols (AAPL and MSFT) across three timeframes (1 minute, 5 minutes, and 1 day).
var hintonData = hinton_map.initHintonData(2, 3)
tickers = array.from("AAPL", "MSFT")
timeframes = array.from("1", "5", "1D")
for i = 0 to array.size(tickers) - 1
for j = 0 to array.size(timeframes) - 1
ticker = array.get(tickers, i)
timeframe = array.get(timeframes, j)
= request.security(ticker, timeframe, [close, close , ta.rsi(close, 14)], lookahead = barmerge.lookahead_on)
percent_change = (close_current - close_previous) / close_previous * 100
rsi_deviation = rsi_current - 50
hintonData.unitMatrix.set(i, j, hinton_map.createHintonUnit(
fillValue = percent_change,
borderValue = rsi_deviation,
innerValue = percent_change * rsi_deviation,
boxText = dv.from_string(str.tostring(math.round(percent_change, 2)) + "%"),
tooltipText = dv.from_string(syminfo.ticker + ", " + timeframe + ": " + str.tostring(math.round(percent_change, 2)) + "%, RSI: " + str.tostring(math.round(rsi_current, 2)))
))
hinton_map.drawHintonMap(hintonData)
