Time cycles are critical in trading, especially in indices futures, as they help traders anticipate periods of increased activity, potential reversals, and significant price movements.
The ATS Discord trading groups provide time cycles in pre-session summary and real-time notifications for traders to stay ahead of the curve.

Here are some other common time cycles that traders often observe:

1. Opening and Closing Sessions:
Market Open (9:30 AM ET):
The market open is one of the most active times of the day, often marked by significant volatility as traders react to overnight news, economic data, and other pre-market developments.
Opening gaps, breakouts, and sharp reversals are common during this period.

Market Close (4:00 PM ET):
The last hour of trading, often called the “power hour,” can see a surge in activity as traders finalize their positions for the day. This period is particularly important for institutional traders and can lead to strong trends or reversals.

2. Mid-Morning Reversal (10:00 AM – 11:00 AM ET):
10:00 AM Reversal Time ( 10am Jiggle):
Often, the market makes its first significant move of the day between 9:30 AM and 10:00 AM ET. By 10:00 AM, traders often witness a reversal or continuation of the initial trend. Economic data releases, such as home sales, consumer sentiment, or manufacturing data, often occur around 10:00 AM, influencing market direction.
11:00 AM Transition:
Around 11:00 AM, the market might consolidate or begin to lose momentum as traders start preparing for the lunchtime lull.

3. End-of-Session Squaring (3:00 PM – 4:00 PM ET):
3:00 PM ET Reactions:
This is another critical time when traders start positioning themselves for the close. Volume often increases as traders who have held positions throughout the day make decisions on whether to hold overnight or close out.

3:30 PM ET Ramp-Up:
The final 30 minutes can be very volatile, with large institutional orders coming in, leading to significant price swings.

4. FOMC (Federal Open Market Committee) Announcements:
2:00 PM ET (FOMC Days):
On days when the Federal Reserve announces interest rate decisions, the market often remains relatively quiet until 2:00 PM ET when the announcement is made. After the release, there can be extreme volatility, followed by the Fed Chair’s press conference.

5. European Market Open (3:00 AM – 5:00 AM ET):
London Open (3:00 AM – 4:00 AM ET):
The London market open is significant because it often brings a wave of liquidity into the market, especially in currency pairs and indices futures tied to European and US markets.
Overlap with Asia and US Pre-Market:
The period between 3:00 AM and 5:00 AM ET sees overlapping trading sessions between Europe and the end of the Asian trading day. This overlap can lead to increased volatility and trend formation.

6. Asia Market Sessions (7:00 PM – 3:00 AM ET):
Tokyo Open (7:00 PM – 9:00 PM ET):
The Tokyo session can influence futures trading, especially in currencies and commodities. It is less volatile than the European and US sessions but still important for setting the tone for the day.
Australia and New Zealand Open:
Before the Tokyo market, the Sydney and Wellington sessions open, marking the start of the global trading day. These markets can have a minor influence on futures trading, especially commodities like gold and oil.

7. Weekly Cycles:
Monday Opening:
Mondays can be unpredictable as traders digest news from the weekend. The market might gap up or down based on weekend developments.
Friday Close:
Fridays often see traders closing positions ahead of the weekend, leading to increased volatility, particularly in the final hours of the trading day.

8. Monthly and Quarterly Cycles:
End of the Month (EOM) Rebalancing:
Institutional investors often rebalance portfolios at the end of the month, leading to increased volume and potential price swings.
End of the Quarter (EOQ) Reporting:
The end of the quarter can see significant rebalancing and window dressing by fund managers, affecting indices futures and other financial instruments.

9. Economic Data Release Times:
Non-Farm Payrolls (First Friday of Every Month, 8:30 AM ET):
One of the most anticipated data releases, the Non-Farm Payrolls report can cause significant market moves, particularly in the first few minutes after its release.
CPI and PPI Reports:
Inflation data like the Consumer Price Index (CPI) and Producer Price Index (PPI) also come out at 8:30 AM ET and can influence market direction.

10. Holiday Seasonality:
Pre-Holiday Rallies:
Markets often experience a rally before major holidays like Thanksgiving and Christmas, a phenomenon known as the “Santa Claus Rally.”

Post-Holiday Sessions:
The day after a major holiday can be quieter, but it may also bring volatility as traders return to the market.

How to use it in trading?
