TradingView Pine editor getting the actual price of a label

Question

I'm trying to get the actual price of a label when it was triggered. I tried a few ways but I'm not able to. Any help would be appreciated. I'm attaching the whole code here now. Maybe you can have a look at it and see where I went wrong. Thank you for all the help.

//@version=4
study("buy/sell", overlay=true)

//Gathers User Inputs
bsSignals = input(true, "Buy & Sell Signals On / Off")

n1 = input(10, "Channel Length")
n2 = input(21, "Average Length")
src = input(hlc3, title="Source")

t = tickerid(syminfo.prefix, syminfo.ticker)
realC = security(t, timeframe.period, close)

//WaveTrend for Signals
ap = src
esa = ema(ap, n1)
d = ema(abs(ap - esa), n1)
ci = (ap - esa) / (0.015 * d)
tci = ema(ci, n2)
wt1 = tci

wt2 = sma(wt1,4)

// Defines Variables for Avoiding Duplicate Signals
var sell = false
var buy = false

// Defines Trade Signals
buySignal = not sell and crossover(wt1, wt2)
sellSignal = not buy and crossunder(wt1, wt2)

if buySignal
    sell := true
    buy := false

    sell := false
    buy := true

Answer 1

I couldn't get my head around what to put in the +tostring() Line 59 and 71.

So I put in wt1 in one and close in the other. As you use the source hlc3 the signal I believe would not fire until the candle is closed making the hlc3 complete.
