Problem with tendency indicator

[Varsanz]

Hello,
Sorry I'm new with this. I've created an EA that buys with the buy signal of the HalfTrend indicator and closes the trade when the sell signal appears. But the program buys and never sells (nor buys again)... Any idea? Thanks!!!!

If the indicator is candle 0 it will work like this, if it is candle 1 it has to change, photo below

candle 1
