Order Book

Bid Side (Buy Orders) - Green

The bid side shows all pending buy orders - traders willing to purchase at prices below the current market price. Key points:

• • Listed in descending order (highest bid at top)
• • Highest bid = best price sellers can get immediately
• • Large bid walls can act as support levels
• • More bids = more buying interest = potential support

Ask Side (Sell Orders) - Red

The ask side shows all pending sell orders - traders willing to sell at prices above the current market price. Key points:

• • Listed in ascending order (lowest ask at top)
• • Lowest ask = best price buyers can get immediately
• • Large ask walls can act as resistance levels
• • More asks = more selling pressure = potential resistance

The Spread

The spread is the gap between the highest bid and lowest ask:

• • Tight spread (0.01-0.05%): High liquidity, easy to trade, low slippage
• • Wide spread (0.1%+): Low liquidity, harder to trade, higher slippage
• • Spread widens during volatile periods or low-volume times
• • Major pairs (BTC/USDT) typically have tighter spreads

Identifying Support/Resistance

Nydar's depth bars highlight large orders clustered at specific price levels that often act as support or resistance:

• • Buy wall: Large bid orders at a price level. Price may bounce here.
• • Sell wall: Large ask orders at a price level. Price may reject here.
• • Watch for walls at round numbers ($50,000, $100,000)
• • Walls can be absorbed if momentum is strong enough

Imbalance Detection

Nydar's imbalance ratio compares total volume on bid vs ask side:

• • More bids than asks: Buying pressure, potentially bullish
• • More asks than bids: Selling pressure, potentially bearish
• • Significant imbalance can precede price moves
• • But imbalance alone isn't a trading signal - needs confirmation

Order Book Dynamics

Watch how the order book changes over time:

• • Orders being added = growing interest at that level
• • Orders being removed = traders canceling (pullback or trap)
• • Large orders disappearing quickly = likely market order filled
• • Spoofing: Large orders placed then canceled to manipulate sentiment

Finding Entry Prices

Use Nydar's bid wall detection to identify potential support for long entries. Place limit orders just above large bid walls where price is likely to bounce. This can get you a better entry than market buying.

Setting Take-Profit Levels

Use Nydar's sell wall visualisation to identify resistance. Place take-profit orders just below large sell walls where price might struggle to break through.

Assessing Liquidity

Before placing a large order, check Nydar's order book depth. If there's not enough liquidity, your order could cause significant slippage. Consider splitting large orders or using TWAP.

Scalping

Scalpers watch the order book for short-term imbalances. When large orders are being absorbed, it can signal imminent price movement in that direction.

Disappearing Walls

A large order appears on the bid or ask side, influencing other traders to act, then vanishes within seconds. If you see a massive sell wall at $50,000 that suddenly disappears as price approaches, it was likely a spoof designed to scare sellers.

Detection: Watch how walls behave as price approaches. Real walls get partially filled. Spoofed walls disappear entirely.

Layering

Multiple fake orders placed at several price levels to create the illusion of deep liquidity. For example, large sell orders at $50,100, $50,200, and $50,300 — all designed to discourage buyers.

Detection: If orders at multiple levels appear and disappear simultaneously, they're likely from the same entity.

Flickering Orders

Orders that rapidly appear and disappear (flash orders). They exist for milliseconds — long enough for algorithms to react but too fast for humans to trade against.

Detection: You'll see the best bid/ask price rapidly changing without any trades executing.

Moving Walls

A large order that keeps moving away from the current price. A sell wall at $50,000 jumps to $50,100, then $50,200 as price rises. The wall is designed to create a ceiling illusion but never actually gets filled.

Signs of an Iceberg

• • Constant refilling: A 10 BTC order at $49,500 gets filled, and immediately another 10 BTC appears at the same price. This repeats multiple times.
• • Price doesn't move: Heavy selling/buying volume at a specific level, but price barely budges. The order book keeps absorbing trades.
• • Disproportionate trade volume: Time & sales shows 500+ BTC traded at a level where the visible order was only 10 BTC. The rest was hidden.

Bullish Confirmation

Strong bids on the order book + large market buy orders on time & sales = real buying pressure. Price is likely to move up. The tape (time & sales) is confirming what the order book is suggesting.

Bearish Confirmation

Heavy asks on the order book + large market sell orders on time & sales = real selling pressure. The tape confirms distribution.

Divergence (Watch Out)

Large bid walls on the order book but time & sales shows mostly sell-side trades executing. The visible bids might be spoofed — real selling is happening despite the apparent demand. This is a bearish signal despite what the order book shows.

Absorption

A large order sits at a level and absorbs incoming market orders without moving. For example: 500 BTC bid at $49,000 — time & sales shows hundreds of BTC selling into it, but the bid stays. This signals strong institutional buying and often precedes a move up.
