Double SAR strategy

Question

I am trying to implement a double sar strategy but couldn't find any answers (maybe I got the answer somewhere but as I am not a coder, I may miss it)

My conditions to open a trade 1)check for PSAR1 if its in uptrend or downtrend 2)check for PSAR2 if it makes a crossover

as per the code, it looks for crossovers on both PSAR1 and PSAR2. I want that the strategy should check for PSAR1 if its in uptrend or downtrend (not if it makes a cross)

Many thanks for any answers.

start1 = input(title="Start1", type=input.float, defval=0.001, step=0.01)
inc1 = input(title="Inc1", type=input.float, defval=0.001, step=0.01)
max1 = input(title="Max1", type=input.float, defval=0.001, step=0.01)

start2 = input(title="Start2", type=input.float, defval=0.001, step=0.01)
inc2 = input(title="Inc2", type=input.float, defval=0.002, step=0.01)
max2 = input(title="Max2", type=input.float, defval=0.005, step=0.01)


PSAR1 = sar(start1, inc1, max1)
PColor1 = PSAR1 < low? color.red:color.red
plot(PSAR1, "ParabolicSAR2", style=plot.style_cross, color=PColor1)

Buy1 = crossunder(close,PSAR1)
Sell1 = crossover(close,PSAR1)

Buy2 = crossunder(close,PSAR2)
Sell2 = crossover(close,PSAR2)

if Buy1 and Sell2
    strategy.entry("BUY", strategy.long)
    alert("BUY", alert.freq_once_per_bar)
    strategy.exit("Buy Exit", from_entry="BUY", profit = tp,loss = sl)

if (Sell1 and Buy2)
    strategy.entry("SELL", strategy.short)
    alert("SELL", alert.freq_once_per_bar)
    strategy.exit("Sell Exit", from_entry="SELL", profit = tp,loss = sl)
