Yes it basically merges two or more deals to average the price of our ‘overall price range’ - what does it means? simple you look at the all chart as one range with a general overall price range.
If we covered already x% deviation with all simultaneous deals and the price keeps moving opposite to our deals we can merge then into one to give the new merged deal a better change to close by TP.
Yes at the moment we can merge the deals manually while in the meantime I suggested an AUTO-Merge feature within a specific price range deviation (% of deviation from the current price)
