Luckily my greed didn't cause me to lose any money, rather prevented me from making around 800.
Some key notes:
We are at a historic (years) support/resistance level.
Jumping the gun (opposite of patience - a key to making it in this game), caused me to sell too early when my study of the futures market has told me to wait a while after the open on Sunday night to place a trade due to certain phenomena.
Signs of weakness, but my trend signals are mixed but majority bullish from last week.
Still short 1991.5 x 1 NQ.
