Hi I'm creating a trading view indicator in pine script, and im using auto fibonacci retracement, problem is I want auto fib to use the last low/high made before the 2 moving averages crossed and then the next fib point to be after cross similar to the chart attached

https://www.tradingview.com/x/L47bSMza/

Here is my code:

study(SUBHAN 2.0, overlay = true)

BullMA = sma(close,50) // Bullish Moving Average
BearMA = sma(close,200) // Bearish Moving Average

BullTrend = (crossover(BullMA,BearMA)) // signifying change of bullish trend when 50 above 200
BearTrend = (crossover(BearMA,BullMA))// signifying change of bearish trend when 200 above 50

plotshape(BullTrend, style=shape.triangleup, color=color.green, transp=40, text=BUY, editable=false, location=location.belowbar, size=size.small)
plotshape(BearTrend, style=shape.triangleup, color=color.red, transp=0, text=SELL, editable=false, location=location.abovebar, size=size.small)

plot(series=BearMA, color= color.red, linewidth=2)
plot(series=BullMA, color= color.green, linewidth=2)

//Auto Fibonacci Retracement code (for the most part stock with a few changes highlighted)

How do I tell it for the first fib point to be before the MA crossed

Any help is apprecieted thanks
