Yes, I like to check the trgger line too (in large timeframes). Well, you will have to make several condition blocks to check:
candle 0's candle close > candle 1's candle close
candle 1 bullish (you can either use the "bull candle" block under various signals or just check for candle 1's open price < candle 1's close price)
candle 2 bullish (same as above)
4)candle 1's candle low > EMA 8 (in case you use constants is period 8 n' method 1)
5)candle 2's candle low > EMA 8
