power hour indicator for TradingView: last hour levels
power hour—the last hour of the trading session—is one of the most active periods for many traders.
but every day, traders manually mark the same levels: high of day and low of day before 3pm. they draw lines, set alerts, and hope they picked the right levels.
the power hour indicator eliminates this manual work completely.
it automatically plots high of day (green line) and low of day (red line) at the start of power hour. no drawing required. no guessing if you marked the right level.
in this article, you'll learn what the power hour indicator plots, how to use it for setting realistic profit targets, what the YM stats tell us about power hour behavior, and how to combine it with other indicators for maximum confidence.

what is the power hour indicator?
the power hour indicator is a TradingView tool that automatically plots high of day and low of day before the last hour of trading begins.
here's what it plots:
- green line: high of day reached before power hour starts (before 3pm ET for NY session)
- red line: low of day reached before power hour starts (before 3pm ET for NY session)
these lines show you the boundaries that price is unlikely to break during the last hour of trading.
what is power hour?
power hour is the last hour of the trading session.
- NY session: 3:00pm-4:00pm ET (last hour of 9:30am-4:00pm session)
- London session: 10:00am-11:00am ET (last hour of 3:00am-11:00am session)
- custom sessions: last hour of whatever session you define
for stocks, power hour is always 3:00pm-4:00pm ET since that's the only trading session.
for futures, forex, and crypto, power hour depends on which session you're trading. if you trade the London session, your power hour is 10am-11am ET. if you trade the NY session, it's 3pm-4pm ET.
why the power hour indicator saves time
without the power hour indicator, you need to:
- identify the high of day before 3pm
- identify the low of day before 3pm
- manually draw lines at both levels
- do this every single day
with the power hour indicator, the levels plot automatically at 3pm. you just look at the green and red lines and know exactly where high and low of day sit.
if you trade power hour regularly, this indicator saves you 5-10 minutes every single day.
YM power hour stats (NY session, last 6 months)
here's the actual data for YM (Dow futures) during the NY session power hour over the last 6 months:
new high of day during power hour:
- NOT made: 70%
- made: 30%
new low of day during power hour:
- NOT made: 85%
- made: 15%
what this tells you
during the last hour of trading on YM, there's a 70% chance price won't make a new high. there's an 85% chance price won't make a new low.
this is critical information for power hour trading:
most of the day's range is already established by the time power hour starts. the last hour typically consolidates or makes small moves within the existing range rather than creating new extremes.
how the power hour indicator works on TradingView
the power hour indicator plots levels automatically at the start of power hour (3pm ET for NY session).
what it plots
- green line (high of day): the highest price reached between session open and power hour start
- red line (low of day): the lowest price reached between session open and power hour start
here's a visual example:
these lines show you the boundaries that price is statistically unlikely to break during the last hour.
updates automatically every day
every trading day at the start of power hour:
- indicator identifies high of day up to that point
- indicator identifies low of day up to that point
- green line plots at high of day
- red line plots at low of day
- no manual work required from you
open your chart at 3pm, and the levels are already there waiting.
understanding the by weekday variance
not all weekdays behave the same during power hour.
for example, you can see Fridays have a much lower probability of making a new high or low during power hour compared to the average stats we’ve shown above:
check the by weekday subreport
before trading power hour, check edgeful's power hour breakout report filtered by weekday.
if it's Wednesday and the data shows 36% chance of new high instead of 20%, you might:
- take profits earlier
- avoid selling calls above high of day
- expect slightly higher probability of breakout
if it's Thursday and the data shows only 18% chance of new high, you have more confidence:
- holding positions near high of day
- selling call spreads above the green line
- targeting high of day aggressively
different days show different power hour behavior. use the by weekday data to adjust your strategy accordingly.
customizing the power hour indicator
the power hour indicator offers a few customization options, though most traders use the defaults.
adjust power hour length
default is 1 hour (3pm-4pm for NY session).
you can change it to 2 hours (2pm-4pm) or any length you want if you prefer a longer "power hour" window.
important: if you change power hour length in the indicator settings, make sure it matches the report settings on edgeful. otherwise your probabilities won't align with your visual levels.
change session
switch from NY to London to Tokyo to match your trading hours.
the power hour indicator recalculates high/low of day based on your selected session.
adjust line colors
customize the green line (high of day) and red line (low of day) to match your chart theme.
some traders prefer more muted colors to reduce visual clutter.
stocks vs futures: using the power hour indicator
for stocks
power hour is always 3:00pm-4:00pm ET since stocks only trade regular hours (9:30am-4:00pm).
the power hour indicator plots high of day and low of day from 9:30am-3:00pm automatically.
straightforward application—no session selection needed.
for futures, forex, crypto
you need to select which session you're trading:
NY session: power hour 3pm-4pm ETLondon session: power hour 10am-11am ET
Tokyo session: power hour varies based on Tokyo trading hours
the power hour indicator adjusts high/low of day based on your selected session.
make sure your indicator settings match the session you're actually trading. if you trade London but have NY selected, your levels will be wrong.
combining power hour indicator with other reports
the power hour indicator works best when combined with other edgeful tools for confluence.
power hour + ATR zones
if ATR zones show 80%+ of ATR used by 3pm, AND the power hour indicator shows high/low of day unlikely to break, you have double confirmation that the day's range is set.
both indicators pointing to the same conclusion: don't expect big moves during power hour.
power hour + previous day's range
if high of day (green line) aligns with previous day's high, that level becomes even stronger resistance during power hour.
example: today's high of day is 43,850. yesterday's high was 43,845. that 5-point zone is now a significant level backed by two different data sources.
power hour + pivot points
when pivot point levels align with high/low of day going into power hour, those become key levels to watch for holds during the last hour.
if R1 pivot is at 43,852 and high of day (green line) is at 43,850, you have pivot + power hour confluence for resistance.
power hour + weekly range
if weekly high aligns with today's high of day going into power hour, that's a multi-timeframe resistance level with even stronger holding power.
stacking probabilities
single indicator: moderate confidence
- power hour + ATR: higher confidence
- power hour + ATR + previous day's range: highest confidence
use the power hour indicator as one piece of your power hour trading strategy, not the only piece.
