One of the most interesting indicator for trend and level lines – fractals. It allow you to see, where candle were on it high/low position, it this current context.
The standart indicator got period of 5 candles, so it check only 2 candles before signal one, and 2 after. But my indicator got period as param, so you can set it as you want.
But dont forget, that this indi, as basic one, got some delay. It draws signal N candles before current candles, where N – your period.
Using it you can clearly see different levels and trend lines. So it can be useful for trend/antitrend trade.
