HOD / LOD: High and Low of Day
Also known as: HOD, LOD, daily high and low, intraday high and low, session high and low
What is it?
The high of day and low of day are simply the highest and lowest prices an instrument has traded so far in the current session. They update live as the day progresses, and by the close they are fixed as that day's range boundaries. They matter far beyond being trivia because of what sits just beyond them.
The break existed to reach the orders above 2418.50. Once they were filled the buying was spent, and the candle closed 6.50 back below the level.
Traders who are long place protective stops under the low of day; traders who are short place them above the high of day; breakout traders queue entry orders on the other side of both. That concentration of resting orders is real liquidity, and in the Smart Money framework it makes the two levels magnets — price often runs just past the high or low, fills that cluster of orders, and then reverses, which is why a clean break of the day's extreme so frequently fails within minutes. A worked case: gold sets a high of day at 2418.50 by mid-morning, drifts, then spikes to 2421.20 in the New York session, triggers the buy stops sitting above 2418.50, and closes the hour back at 2412.00 — the break existed only to reach those orders.
The distinction to keep straight is that these are today's live, still-moving extremes, while previous day high and low are yesterday's completed, fixed levels; both act as liquidity, but only one of them can still change under you.
Why it matters: Stop orders cluster just beyond the day's extremes, so these two levels are where price most often reaches for liquidity before reversing.
They mark where the day's resting orders sit, which drives both genuine breakouts and the failed ones.
Real-world example
Gold sets a 2418.50 high of day, later spikes to 2421.20 to trigger the buy stops above it, then closes the hour back at 2412.00.
How SignalBots handles it
SignalBots signals include the stop and target levels behind each setup, so you can see whether an entry sits above or below the day's extremes before you take it. See /risk-warning.
Pro tip
Wait for a candle to close beyond the day's extreme rather than trading the tick that breaks it — the difference separates a real break from a stop run in most sessions.
Common pitfalls
Placing a stop a pip or two beyond the high or low of day, exactly where the resting orders are, so an ordinary liquidity sweep takes you out.
Frequently asked questions
How is HOD different from previous day high?
The high of day is today's live extreme and can still move; the previous day high is yesterday's fixed, completed level. Both attract resting orders, but only today's can change while you are in a trade.
When does the trading day start for these levels?
It depends on your platform's server time, and in forex the daily candle typically rolls over at 17:00 New York time. Confirm your chart's session start, because a different rollover produces different daily extremes.
Why does price so often reverse after breaking the day's high?
Because the break itself fills the cluster of buy stops sitting above it. Once those orders are absorbed, the buying that drove the spike is exhausted, and price can fall back through the level it just cleared.
Should I trade breakouts of the daily extremes?
Some strategies do, but they need a filter for failed breaks — typically a close beyond the level, or a retest that holds. Trading the raw first touch means routinely buying the top of a stop run.
Can a bot use HOD and LOD?
Yes, both are trivial to compute from intraday data and are common inputs for breakout and mean-reversion rules. Automation does not make them more reliable, and every such trade puts your capital at risk. See /risk-warning.
Trading involves substantial risk of loss. Historical and backtested results do not guarantee future performance. Read the full risk warning.
