1). For me it is easier to interprete Babon Slope than trix. Babon Slope is one line, trix contains two lines and I'm very suspicious about any arrows, crosses etc. With Babon Slope it is really simple, it is either red or white, and on M1 we want something simple, something we can understand with just one look.
2). trix doesn't interact with the Japanese candles, Babon Slope interacts with Japanese candles, and it is important: I want to see not only the color, but also whether the price is above/under the line, it is important for the exits.
