I'm finding that it will take a long or short position, but it's not based on when the EMA crosses. I have it set for the default, 1 and 5, but it will take a position for no apparent reason, even if it does not cross. I don't understand the logic behind it, or why it takes a trade when it does. I've even seen it cross and watch it NOT take a trade one way or the other.

Can someone PLEASE enlighten me on this one?
