Condition to buy using wick on the bottom.

[fabiobioware]

I would like to open a purchase according to the image settings.

I have 3 moving averages.
I want that if the previous candle (1) made a wick on the bottom of the candle and this wick touched or is crossed in the moving average that this is a "buy signal", the purchase should only happen if the current candle (0) is a buy candle (green).

How can I create this condition, can someone give me examples?
