Dears members,

Please find here below a screener to identify the Morning and Evening stars. As you know, these candlestick structures are very relevant to identify the top and bottom of a trend. It’s also a strong buy and sell signal.

This code has been update to stick as much as possible to the theory of candlestick.

Do not hesitate to contact me or consult my website Boursomaniac for other strategies.
