For those who may be interested: I have successfully transitioned from day-trading stocks to day-trading options @avi style. I ONLY buy calls or puts for day-trading. There are videos from @Megan and @Avi in the bbt education center about this approach and the advantages of day-trading options vs stocks such as lesser capital requirements etc.
Thank you @megan and @avi.

Also, I have made the transition from DAS-TDA to thinkorswim(tos). The main misconception out there is that the FILLS in tos are worse than that of DAS. However after couple of years of DAS-TDA and comparing my experience to tos, I can assertively say that the tos fills are not that bad especially for day-trading options. The main things that are missing from tos is a good Level 2 and scripting like DAS has. If you get Bookmap, the Level2 void can be overcome. Since I am day-trading options, the Active Trader on tos works well and I am not missing the use of scripts.
