ta.crossover does not work as expected in pine script

I have the following script

//@version=5
strategy("Bollinger Bands Strategy", overlay=true)
// BB
source = close
length = input.int(20, minval=1)
mult = input.float(2.0, minval=0.001, maxval=50, title="StdDev")
basis = ta.sma(source, length)
dev = mult * ta.stdev(source, length)
upper = basis + dev
lower = basis - dev

// Stoch
periodK = input.int(14, title="%K Length", minval=1)
periodD = input.int(3, title="%D Smoothing", minval=1)
smoothK = input.int(1, title="%K Smoothing", minval=1)
k = ta.sma(ta.stoch(close, high, low, periodK), smoothK)
d = ta.sma(k, periodD)
lcb = input.int(20, title="Long border cross", minval=1) // long condition bollinger
scb = input.int(80, title="Short border cross", minval=1) // short condition bollinger


long_condition = (k[2] < k[1]) and (k[1] < k) and ((k[2] + k[1] + k) / 3) < 20
plotchar(long_condition, "long?", "", location = location.top)
short_condition = (k[2] > k[1]) and (k[1] > k)  and ((k[2] + k[1] + k) / 3) > 80
plotchar(short_condition, "short?", "", location = location.top)
plotchar(source, "source", "", location = location.top)
plotchar(lower, "lower", "", location = location.top)
my_crossunder = (source[1] > upper[1]) and (source < upper) 
plotchar(my_crossunder, "my_crossunder", "", location = location.top)

if (my_crossunder)
    strategy.entry("BBS", strategy.short, stop=upper, oca_name="BollingerBands", oca_type=strategy.oca.cancel, comment="BBS")
else
    strategy.cancel(id="BBS")

and for some reason, it does not enter my if condition, while plotchar(my_crossunder, "my_crossunder", "", location = location.top) says the variable is true

Plot

Here at the screenshot, it has to enter the position, but it does not do, while the condition is true, why?

Solved it, strategy.entry() can not open more, than one position with the current strategy. So it means I had previous order opened with the same strategy. More info here. So if you want to place order anyway you should use strategy.order()
