There's a way of telling. If you have an 8 EMA and 30 EMA. If both of these are below that trendline and the 8 crosses the 30 then it will be a bullish breakout.
If the 30 EMA is north of that trendline then price will follow that trendline down to drag down the 30 EMA.
When you draw another trendline if both the 8 EMA and 30 EMA are below that trendline. When the 8 crosses the 30 you will get a bullish breakout. 5/8/26
The 30 must be above the 8 and the 8 must cut up through the 30 and it has to do that before reaching the trendline. In this case, the 30 is above the trendline and the 8 cannot cross it before it reaches the trendline. 5/8/26
Why did you draw it like that? The trendline should be wick to wick or candle body to candle body. You have to redraw a trendline every time there is a new high until the cross happens from underneath. 5/8/26
Oh yes! There's one other rule! After the 8 crosses the 30. The 8 must cut through the trendline. If it doesn't cut through the trendline there is no cigar. 5/8/26
For the bullish breakout to work. The 8 must cross the 30 and then the trendline itself. This works better during RTH (real time trading hours when the exchange is open during office hours). It doesn't work so good in the middle of the night. Except when the market was closed and re-opens. It works really good when there's been a gap. 5/8/26
