Looking to create a pine script strategy that uses 2 existing indicators (SSL Channel & CCI) and creates a Buy/Sell alert when 2 parameters are met

Question

I have no idea what I am doing but the idea seems simple to code especially using the existing below code, but I dont know how to create the long/short signals. I basically want to the 2 strategies to coexist with each other and create a LONG signal when the SSL channels cross up AND when the CCI crosses up over -100 and a SHORT signal when SSL channels cross down AND when the CCI crosses down 100.

It's laid out in this video: https://www.youtube.com/watch?v=FnnPbVhGoBk starting around 4:57 - (sincere apologies for the awful robot voice)

//SSL
study("SSL channel", overlay=true)
period=input(title="Period", defval=10)
len=input(title="Period", defval=10)
smaHigh=sma(high, len)
smaLow=sma(low, len)
Hlv = na
Hlv := close > smaHigh ? 1 : close < smaLow ? -1 : Hlv[1]
sslDown = Hlv < 0 ? smaHigh: smaLow
sslUp   = Hlv < 0 ? smaLow : smaHigh

plot(sslDown, linewidth=2, color=red)
plot(sslUp, linewidth=2, color=lime)

//CCI
indicator(title="Commodity Channel Index", shorttitle="CCI", format=format.price, precision=2, timeframe="", timeframe_gaps=true)
length = input.int(20, minval=1)
src = input(hlc3, title="Source")
ma = ta.sma(src, length)
cci = (src - ma) / (0.015 * ta.dev(src, length))
plot(cci, "CCI", color=#2962FF)
band1 = hline(100, "Upper Band", color=#787B86, linestyle=hline.style_dashed)
band0 = hline(-100, "Lower Band", color=#787B86, linestyle=hline.style_dashed)
fill(band1, band0, color=color.rgb(33, 150, 243, 90), title="Background")

ma(source, length, type) =>
    switch type
        "SMA" => ta.sma(source, length)
        "EMA" => ta.ema(source, length)
        "SMMA (RMA)" => ta.rma(source, length)
        "WMA" => ta.wma(source, length)
        "VWMA" => ta.vwma(source, length)

typeMA = input.string(title = "Method", defval = "SMA", options=["SMA", "EMA", "SMMA (RMA)", "WMA", "VWMA"], group="Smoothing")
smoothingLength = input.int(title = "Length", defval = 5, minval = 1, maxval = 100, group="Smoothing")

smoothingLine = ma(cci, smoothingLength, typeMA)
plot(smoothingLine, title="Smoothing Line", color=#f37f20, display=display.none)```
