Thank you, Admin,What do you mean by a crossover failure?
What I am trying to say here is that, for example, when the Green line and the Red line are trying to crossover, either for buy or sell, for instance, once the arrow shows on Candle A and the crossover condition did not occur on that particular candle A, the arrow will remain on that candle A without actual crossover. Therefore, maybe the crossover still tries Candle B, and C and did not occur on those Candles (A, B, & C), arrows will appear on those Candles. Now, let's say the crossover eventually occurs on Candle D seen and confirmed, by the time I refreshed the chart those arrows showed on the previous candles (A, B & C) will disappear but the actual crossover on Candle D will remain.
