Inverse FVG (IFVG): Trading a Failed Gap on US30

An inverse fair value gap (IFVG, also called an inversion gap or inversion FVG) is a fair value gap that price has closed straight through, and that then works from the other side. A failed bullish gap becomes resistance; a failed bearish gap becomes support. It is the old "support becomes resistance" flip, applied to a gap.

This guide covers what a fair value gap is, what makes one inverse, and a complete rule set for trading it on US30, with a worked example using real price levels.

Key takeaways

• —A fair value gap is a three-candle pattern where the first and third candles' wicks do not overlap.
• —A gap becomes inverse only when a candle body closes through it. A wick through it is a test, and the gap held.
• —The sell version needs a downtrend: lower highs, lower lows, and a bearish gap price has already respected.
• —The entry is the overlap between the failed bullish gap and the new bearish gap that forms on the way down.
• —The stop goes above the swing high, the target at the next low, and a close back above the zone ends the idea early.

What is a fair value gap?

A fair value gap (FVG) is a price range that one fast candle moved through so quickly that the candles either side of it never overlap. It takes three candles:

• —In a bullish gap, the high of candle 1 sits below the low of candle 3. The space between them is the gap.
• —In a bearish gap, the low of candle 1 sits above the high of candle 3.

Traders watch these ranges because price often comes back to them. A bullish gap usually marks where buyers stepped in hard, so a return to it can look like a buy.

What makes a gap inverse?

A gap becomes inverse when price closes straight through it in the wrong direction. For a bullish gap, that means a candle body closing below the gap's bottom.

The close is what counts, not the wick. If the gap runs from 42,080 to 42,120 and a candle drops to 42,060 but closes at 42,095, it only tested the gap: the close is still inside, and the gap held. Only a close below 42,080 makes it a failed gap.

Why a failed gap flips

A bullish gap that fails leaves traders on the wrong side. People who bought inside the gap are now losing, and many will sell to get out near their entry when price comes back up. That selling is what can turn the old support into resistance.

"Can" is the important word. A failed gap often acts as resistance; it does not always. That is why the rules below add a trend filter, a second confirming gap and a defined way out.

The bearish IFVG setup, step by step

1. 1.Trend first. Only take it in a downtrend: lower highs, lower lows, and a bearish gap that price has already respected.
2. 2.The fail. A candle body closes below the bottom of a bullish gap.
3. 3.The new gap. On the way down, price leaves a new bearish gap. When it sits on top of the failed bullish gap, the part where they overlap is the entry zone.
4. 4.The entry. Sell in the overlap, at its middle.
5. 5.The stop and target. Stop just above the swing high that started the drop. Target the next low below.
6. 6.The early exit. If a candle closes back above the zone, the idea is wrong: get out, even before the stop.

A worked example on US30

These levels are the 15-minute US30 example from our free Inversion Gap lesson.

The trend: highs stepping down from 42,320 to 42,240 to 42,170, and a rally into the 42,222 to 42,250 bearish gap that turned back down. The setup is allowed.

To find the overlap, take the higher of the two bottoms (42,088) and the lower of the two tops (42,120). The risk is 42,178 − 42,104 = 74 points; the reward to 41,930 is 174 points. The trade pays about 2.4 times what it risks, before costs.

The bullish version

The same idea works in reverse. In an uptrend (higher highs, higher lows), a candle body closes above the top of a bearish gap. The failed bearish gap can then act as support. Look for a new bullish gap overlapping it, buy in the overlap, put the stop below the swing low that started the rally, and target the next high. A close back below the zone ends the idea.

Five mistakes that turn it into a coin flip

• —Counting a wick as a fail. A wick through a gap is a test that held. Wait for the body to close through.
• —Ignoring the trend. In an uptrend, a close through a bullish gap is more often a pullback than a turn.
• —Chasing the breakdown candle. Selling the candle that broke the gap puts the entry far from the stop. The overlap gives a better price and a defined risk.
• —Holding after a close back above the zone. That close is the market saying the flip failed. Waiting for the stop just costs more.
• —Taking it every single time. No setup wins every time. The rules decide when to take it; the stop decides what a loser costs.

Which timeframe works best?

The example uses 15-minute candles, and the logic is the same on any timeframe. Gaps on the 15-minute and 1-hour charts are built by more trading than the dozens of tiny gaps a 1-minute chart prints every session, so they are easier to see and to act on. Whatever you choose, use the same timeframe for the gap, the trend and the stop.

Is the IFVG a proven edge?

Not on our evidence yet. This is a rule set with a clear trend filter, entry, stop, target and exit, which makes it testable. It is not a tested edge. We have not published a backtest of these exact rules, and a few good-looking examples prove nothing either way.

Before trading it with real money, test it the honest way: fix the rules first, include costs, and judge the result on data you did not use to design them. Our lesson We Backtested It: The VP Strategy shows that process on a strategy that looked good and lost. Then forward test it on the free live US30 simulator, with prop-firm rules and no money at stake.
