The bars
The gaps
The last bar gapped up 0.48% from the close of 458.56, and it has not come back to that close yet. In these bars, 47% of up gaps filled on the bar they opened.
- Gaps up
- 15 up gaps, 0.37% on average: 47% filled the same bar, 64% within 5 bars.
- Gaps down
- 21 down gaps, 0.33% on average: 62% filled the same bar, 89% within 5 bars.
- By size
- Gaps up to 0.32% filled the same bar 83% of the time; bigger gaps 28%. Big gaps often carry news, and news gaps fill less.
- The open gap
- The nearest unfilled earlier gap is a fall from 464.54, 3 bars ago; price has not traded back there since. That close sits 0.82% above the last close, and many traders watch it as a target.
- Read it with care
- A gap fills when price trades back to the close before it. These rates describe the bars you pasted. A fade of the gap needs a stop, because the gaps that do not fill tend to run.
The last gaps: the size from the previous close, that close, and when price came back to it. The last bar is marked.

Simulated results are hypothetical and have limits: real trading has slippage, gaps, changing results and emotions. Trading leveraged products can lose money quickly, including all of it.

Do gaps always fill?
A gap opens when a market starts the day away from where it closed, after news or an overnight move. An old saying holds that gaps always fill. Many do, and fast; others never come back, and those are often the start of a trend. This page counts, in your own bars, how many gaps up and down came back to the previous close on the same bar or within five, splits them by size, and shows the nearest gap that is still open.
Plan for the overnight jump itself with the gap risk check, see the usual daily range with the daily range check, and size the trade with the position size calculator.
Not advice. Counts on the bars you type; how gaps filled in the past does not promise how the next one will.
