How-to-create-Bollinger-Band-Squeeze-strategy

Hello :)

Is there anyone here that can help me get this strategy in code for WealthDeveloper, or help me create it in drag and drop?

What I need is an indication of when the BB is squeezed in a certain stock, and then initiate buy signals when the stock breaks the upper or lower band.... I'll add a screenshot of a real case, so you get an idea :)



Here is the code from tradingview:

study("1337 Squeeze", overlay=true)

ma_len = input(20, "MA length")
atr_len = input(14, "ATR len")
atr_mult = input(1.5, "ATR multiplier", step=0.1)
std = input(2, "BB stdev", step=0.1)

[basis, bb_up, bb_down] = bb(close, ma_len, std)
atr = atr(atr_len)
k_up = basis + atr * atr_mult
k_down = basis - atr * atr_mult

squeeze = bb_down > k_down and bb_up < k_up
breakout = (squeeze and close > bb_up) or (squeeze and close < bb_down)

plot(basis, color=breakout?color.red:squeeze?color.green:na, linewidth=2, style=plot.style_cross)
plot(bb_up, color=color.red, linewidth=1, transp=100)
plot(bb_down, color=color.red, linewidth=1, transp=100)
plot(k_up, color=color.blue, linewidth=1, transp=100)
plot(k_down, color=color.blue, linewidth=1, transp=100)
