Trading Slang, Defined: 13 Tags and Their Rules

FOMO'd in, bought the top, paper hands, round-tripped, diamond hands — how ColdRead turns thirteen pieces of trading slang into rules with ATR thresholds.

Why thresholds are in ATR

"Sharp run-up", "deep drop", "was in profit" all need a yardstick that stretches with the market. Percentages do not work: a crypto pair can swing 30% in a day while a large-cap needs two weeks for 2%. One fixed 2% threshold fires on every trade in one market and never in the other.

ATR is the market's own unit of movement — true range is the largest of the bar's range, its high against the prior close, and its low against the prior close, smoothed over 14 bars.¹ Written as ATR multiples, "2 ATR" means the same thing everywhere: price travelled two normal sessions' worth of distance in that direction. Every ATR below is the 14-bar value inside the replayed segment, read at the entry bar (or the exit bar, where stated).

Entry: where you bought

FOMO'd in

Fires when the entry bar closes more than 2 ATR above the close three bars earlier.

Misread: it does not take three up bars — one long candle covering 2 ATR is enough, and six slow bars that never reach it do not fire. The rule reads where you entered, not how it ends; chases inside strong trends win all the time.

Bought the top

Fires when both hold: within the first 5 bars after entry (or up to the exit, if earlier), the high never gets 0.5 ATR above your entry; and while you hold, the low breaks 2 ATR below it.

Misread: this is not the same tag as chasing, and it appears on its own — a failed breakout at the end of a range buys the top without any chase. A pop that clears 0.5 ATR before collapsing is not this tag either; that is a round trip.

Caught a falling knife

Fires when the 20 closes before your entry have a negative least-squares slope and your entry closes below their mean — that is the downtrend test — and the low afterwards breaks 2 ATR below your entry. Fewer than 20 prior bars, no verdict.

Misread: "buying in a downtrend" is not enough. Buy the actual turn, never take 2 ATR of heat, and the tag stays off.

Bought the bottom (positive)

Fires when price never trades below the low of your entry bar again, and the highest close while you hold is more than 2 ATR above your entry.

Misread: it means your entry bar was the floor of that move, not that you called the all-time low. It is the same action as the falling knife, with the other ending.

Averaging down

Fires when two long trades exist, the second entered while the first was still open, and the second entry bar closed below the first trade's entry price. There is no size or loss threshold.

Misread: the rule cannot read intent — planned scale-ins and grid buys fire it just the same, and so does an add that ends up profitable. It describes exposure growing in the losing direction. The tendency to add to losers is well documented in brokerage account data.²

YOLO'd in

Fires when the first long trade of the session used 100% of the position.

Misread: it has nothing to do with the outcome, only the size of that first entry. What it marks is a state: no second chance.

Exit: where you sold

Paper hands

Fires when a manual exit — stops, take-profits and holding to the end of the session are all excluded — is followed within 8 bars by a close more than 2 ATR above your exit price (ATR read at the exit bar).

Misread: it does not mean you were wrong. A planned take-profit that the market runs past fires it too; the rule measures distance, not reasons. A rally starting on bar 9 does not count. Behavioral finance calls the tendency to sell winners early and ride losers the disposition effect³; this tag is one instance of the first half.

Panic sold the bottom

Fires when your exit price sits in the bottom 10% of the high-low range of the next 8 bars. No ATR here — the yardstick is the range the market itself draws afterwards.

Misread: manual, stop and take-profit exits are treated alike; it describes a location, not your discipline. If the decline simply continues, your exit lands near the top of that range and nothing fires — this tag only shows up when the selling stopped right after yours did.

Honored the stop (positive)

Fires when at least one long was taken out by a stop, and every losing long lost no more than the stop-distance cap (15% of entry price by default).

Misread: it does not reward not losing. It rewards losses that stayed inside a distance you set in advance — one runaway loss costs the whole session this tag.

Result: how much of the move you kept

Round-tripped

Fires when the highest close while you held was more than 2 ATR above your entry, and the trade returned zero or less. Breakeven counts.

Misread: closes only, intraday spikes do not count. Against paper hands: a round trip never left, paper hands left early — one rides profit back to zero, the other watches from the sidelines.

Diamond hands (positive)

Fires when the long closes green and the gain you kept is at least 70% of the best close-to-entry gain available while you held.

Misread: it is not "only the exact top counts". The 70% line exists because tops are unknowable in real time, and reaching for the last 30% is how held winners become round trips. Drawdowns along the way are not punished.

Flat: doing nothing is also a call

Missed the rally

Fires when you take no trade at all in the session and price rises more than 3 ATR from the end of the warm-up.

Misread: it only applies to a completely flat session. Trading small is not this tag.

Dodged the drop (positive)

Fires when you take no trade at all and price falls more than 3 ATR from the end of the warm-up.

Misread: it is the mirror of missing the rally — the same "did nothing", judged two ways by the market that followed. Which is exactly why one tag proves nothing.
