I generally have 2 methods for shorting:
One is to short low volatility b, directly opening a large position with a small stop loss. Either chase after a breakout or open when there is resistance on the trend line.
The other is to short high volatility imitation b, usually waiting to do a second high after the peak, not shorting if there are no upper shadows, and not shorting if the negative rate is too high. Start with a small position. Once there is a price advantage, begin rolling the position, betting on a spiral decline.
Shorting is difficult; to make significant profits, you can only roll positions. It is not advisable to play with monthly contracts. You might end up rolling to the end, only to face a big rebound and lose everything.
Also, some people can become addicted to shorting and habitually short even when a bull market comes.
