Quote from trader_david:
gap up is not the signal to go short. 50% gain or 100% rally is not the signal to go short.
trading is all about inequilium between buyers and sellers.
SEED was trending very well today. I will look for support to buy in this kind of runaway crazy market.
your ego is too strong. before the market, we as a trader, need be humble, we must know when we are wrong and negnate our wrong view, reverse ourself and befefit from the market.
you are afraid of "no shares to short". I have this experience, back to 2005, I remebered I was shorting CAAS, scottrade (at that time I was with) just had 500shares when I decided to go short, so I naiively toke the short, CAAS went from 6 to 8, then 9, and I tried to short at that price, scottrade killed my old short becuase it met scottrade's short selling margin limit(over 20% or 3 dollars, I do not remeber, they will kill it for you), I was mad, lost $1.6k+, glad they do not have shares for me to short in the rally, otherwise, I got the same results as you.
you need think in a little bigger picture, one day's rally is just a tiny bar in a monthly chart. if seed shoots another 3 points tomrrow, it will not be a surprise, just a tiny bar!
if you just trade intra-day chart, then must define your timeframe within 5minutes or 1 minutes bar, if how many bars passed, the market is still not in your favor, that means yoour trade is invalid.
good luck
