Como está a atmosfera do mercado agora? Deveria dizer que a temporada de alta ainda não chegou, mas os touros não foram embora.

Why I say it's hard to short at high positions; the high itself is an upward trend, and going short is against the trend. Many times, just a few candles can bring it down. It's hard to grasp the timing. After a big drop, people want to take a look at the pattern, but the result is that someone picks the bottom and a few bullish candles push it back up. I have never seen anyone who shorted at high positions with Martingale survive for a year; they all get blown up when the market turns bullish.
