Displaying label on hovering mouse in Pine Script

Question

I have several indicators overlayed on each other, I need to know the data of specific indicator on hovering mouse on it.

Here is the code (I'm two days in programming):

    //@version=5
indicator(title="Moving Average Convergence Divergence", shorttitle="MACD", timeframe="", timeframe_gaps=true)

// WMA Timeframes
Chart = request.security("BINANCE:BTCUSDT", "", (ta.wma(close, 10)))
WMA20 = request.security("BINANCE:BTCUSDT", "20", (ta.wma(close, 10)))
WMA30 = request.security("BINANCE:BTCUSDT", "30", (ta.wma(close, 10)))
WMA40 = request.security("BINANCE:BTCUSDT", "40", (ta.wma(close, 10)))
WMA50 = request.security("BINANCE:BTCUSDT", "50", (ta.wma(close, 10)))
WMA60 = request.security("BINANCE:BTCUSDT", "60", (ta.wma(close, 10)))
WMA70 = request.security("BINANCE:BTCUSDT", "70", (ta.wma(close, 10)))
WMA80 = request.security("BINANCE:BTCUSDT", "80", (ta.wma(close, 10)))
WMA90 = request.security("BINANCE:BTCUSDT", "90", (ta.wma(close, 10)))
WMA100 = request.security("BINANCE:BTCUSDT", "100", (ta.wma(close, 10)))
WMA110 = request.security("BINANCE:BTCUSDT", "110", (ta.wma(close, 10)))
WMA120 = request.security("BINANCE:BTCUSDT", "120", (ta.wma(close, 10)))
WMA130= request.security("BINANCE:BTCUSDT", "130", (ta.wma(close, 10)))
WMA140 = request.security("BINANCE:BTCUSDT", "140", (ta.wma(close, 10)))
WMA150 = request.security("BINANCE:BTCUSDT", "150", (ta.wma(close, 10)))
WMA160 = request.security("BINANCE:BTCUSDT", "160", (ta.wma(close, 10)))
WMA170 = request.security("BINANCE:BTCUSDT", "170", (ta.wma(close, 10)))
WMA180 = request.security("BINANCE:BTCUSDT", "180", (ta.wma(close, 10)))
WMA190 = request.security("BINANCE:BTCUSDT", "190", (ta.wma(close, 10)))

// MACD inputs
fastLength = input(title="Fast Length", defval=20)
slowLength = input(title="Slow Length", defval=50)
signalLength = input.int(title="Signal Smoothing",  minval = 1, maxval = 50, defval = 15)

// Calculating
tf = input.string(title="WMA Source Timeframe", group="MACD 1", defval="Chart", options=["Chart", "20", "30", "40", "50", "60", "70", "80", "90", "100", "110", "120", "130", "140", "150", "160", "170", "180", "190"])
timeframe_ = tf == "Chart" ? Chart : tf == "20" ? WMA20 : tf == "30" ? WMA30 : tf == "40" ? WMA40 : tf == "50" ? WMA50 : tf == "60" ? WMA60 : tf == "70" ? WMA70 : tf == "80" ? WMA80 : tf == "90" ? WMA90 : tf == "100" ? WMA100 : tf == "110" ? WMA110 : tf == "120" ? WMA120 : tf == "130" ? WMA130 : tf == "140" ? WMA140 : tf == "150" ? WMA150 : tf == "160" ? WMA160 : tf == "170" ? WMA170 : tf == "180" ? WMA180 : tf == "190" ? WMA190 : na
src = timeframe_
macd = ta.ema(src, fastLength) - ta.ema(src, slowLength)
signal = ta.ema(macd, signalLength)
hist = macd - signal
plot(hist, title="MACD 1", style=plot.style_line, color=(hist>=0 ? (hist[1] < hist ? color.green : color.green) : (hist[1] < hist ? color.red : color.red)))

Here is how I use indicator (overlaying several): Screenshot

I need to see the “WMA Source Timeframe" value in label when hovering mouse on the line of circles of one of MACDs to distinguish them.

Thank you!
