The times that I can remember entering a trade off a delta zone of support or resistance and then having to bail fast at a loss is when unexpected news hits. If I have sold positions into a return of price to a delta NET Short Holders zone and price then bounces off everything is fine. Now if unexpected news comes out that causes a major shift in sentiment just after I entered the trade, I will then see realtime aggressive INITIATED buying through the delta zone of resisitance (as the zone of sellers frantically bailout of their held inventory). This is the type of scenario where I would have a few points loss as I rid my positions during this INITIATED buying rush, which causes the zone to quickly go neutral.
I have had some good LONG intraday delta signals with each new low.....keeping me busy this a.m.
