@baccicin Yes, you can do that. However, buiding buttons is always more complicated than plotting arrows. I strongly recommend you to begin with arrows. Do you have any initial project to do it?
@baccicin That depends on what you exacly want. You current configuration is searching for crossinf on candle ID 1 while you apparetly are looking for crossings on highs/lows. Could you please provide a more detailed list of conditions to be met?
