  3. Calculate the (C-L)/(H-L) ratio every day (IBS).
  4. Calculate a band 2.5 times below the 10 day high using the average from point number 1 (ATR). Ie, subtract number 1 (2.5 times) from number 2.
  5. If SPY closes below the band in number 4, and point 3 has a lower value than 0.5, go long at the close and exit on tomorrow’s open.

– What is an overnight trading strategy, and how does it work in the S&P 500?

An overnight trading strategy involves entering a trade at the market’s close and exiting it at the following day’s open. In the case of the S&P 500, this strategy uses specific criteria, such as Average True Range (ATR) and the IBS ratio, to determine entry and exit points.

– What are the key criteria used in the S&P 500 overnight trading strategy?

The criteria include calculating the ATR (a 25-day average of the High minus Low), the high of the last 10 days, the IBS (C-L)/(H-L) ratio, and a band below the 10-day high. If the SPY closes below this band and the IBS is below 0.5, a long position is entered at the close and exited at the next open.

– Is the overnight trading strategy in the S&P 500 applicable to both long and short positions?

The strategy is designed for long positions, and a vice versa approach for short positions does not yield favorable results.
