I think this system can be modified and used to trade ETFs. Am I correct Murray?

Quote from chvid:
Hi.
I have been running an interactive brokers automated trading system for while using the ETFs SPY and SH. Where SH is an unleveraged inverse to SPY.
I use market orders and I trade around 5 times a week.
Using interactive brokers what would be the advantages / disadvantages of shorting SPY instead of going long SH?
Wrt. for example bid/ask spread, order execution, fees and interest.
Is there a preferred way if I wish to take a short position on the S&P500?
