Trading Calendar spreads

I’ve been trading calendars 1 or 2 at a time with about 3-4k total in starting account value and have had crazy success. I’m not planning any entries, just picking an equity and trying it out. I’ve only had one losing trade and it was because of a mistake in my spreadsheet that made me think I was in the green on the trade when I actually wasn’t. Through rolling, any losing trades that I have had, I’ve been able to recover into winners. I’ve been actively trading options for about 3 years now and every time I think I’ve cracked the code on trading, something I have overlooked bites me in the ass, was wondering if you guys could give your thoughts? I’d be happy to answer questions and I can show individual trades of any of these as I have a separate sheet tracking each individual trade!
