Speculative short of SP500

Based on rising wedge I feel an urge to short SP500. I do not have enough liquidity in the account where I can trade futures + my broker does not allow stops when trading futures. I will use leveraged ETF with stops SPXU.

While I was writing the price began moving so I had to urgently execute the trade. Will write a summary in comments.

I made a severe mistake by breaking 3 rules:
- no intraday trading
- always SL
- limit risk exposure at 1% per trade

Violating these rules cost me more than 1% of my capital today.
