Module 4 · Scalping, Limits & Exam
Final Exam
Mixed questions across the whole course. Aim for SHARP (≥90%).
In this lesson you'll
- Synthesize DOM and tape reading end to end
- Read ladders and aggression under exam conditions
- Confirm you're ready to study a live order book
No new material — this exam mixes everything: the ladder, how price ticks, the tape, aggressor side, stacking/pulling, icebergs, absorption, spoofing and the limits. Your score saves automatically.
Final exam
Answer all questions. Each is graded instantly with an explanation.
Why that's off: It's reversed.
Why that's off: Both relate to orders/trades, not a price/volume split.
Why that's off: They show different data.
The DOM is the resting order book (intent that can be cancelled); the tape is the stream of executed trades (facts). Cross-checking the two is the core skill.
Why that's off: Buying aggression prints at the ASK.
Why that's off: Every trade has an aggressor.
Why that's off: The taker (aggressor) initiated, not a passive maker.
A print at the bid means a taker hit the bid — an aggressive seller. That's bearish pressure (often red).
Why that's off: Eating offers moves price up.
Why that's off: Consuming the inside offer moves the inside ask.
Why that's off: It moves to the next level, one tick, not a gap.
Once the inside offer is eaten, the next-higher offer becomes the best ask — price has ticked up. Price moves when a side's resting liquidity is consumed.
Why that's off: That's bids-pull + offers-stack.
Why that's off: It's a directional read, not flat.
Why that's off: The interaction clearly leans up.
Sellers pulling (retreating) plus buyers stacking (committing) is a bullish lean. The mirror points down.
Why that's off: A spoof never trades; this trades heavily.
Why that's off: Exhaustion is shrinking volume; this is heavy.
Why that's off: A pulled order vanishes; this absorbs and holds.
Volume far exceeding the visible size, with the level holding, is the iceberg signature — hidden size refilling and absorbing the aggression.
Why that's off: Size is what a spoof fakes.
Why that's off: Color is just side.
Why that's off: The spread doesn't determine authenticity.
Size alone can be spoofed. A wall that's traded into and survives is real; one that's pulled before being hit, with no prints, was never liquidity.
Why that's off: Lit orders are what it shows.
Why that's off: Best bid/ask are visible.
Why that's off: Depth is its core display.
The DOM only shows lit orders. Hidden iceberg reserves, stop orders (invisible until triggered), and dark-pool/off-exchange interest don't appear — a key limitation.
