simple crossover logic

[olatrader]

hi,

I'm trying to set an arrow on each (from red to green) crossover in my indicator and have a condition set when buffer2 > buffer3
Unfortunately i get the arrows on strange places.
any ideas what im doing wrong?

Crossing do not work well with candle ID 0. This is why it works fine with candle ID 1. Remember that ID 0 means the current candle which is still under construction. Maybe your condition is true at the beginning of the candle but not at the end. That cannot happen with ID 1 because that candle will never change.
