Topic 13: Buyers and Sellers (The Footprint)

Four Types of Market Participants

Aggressive Buyer

  • Bought the OFFER (ask price) — paid market price to get in
  • Willing to pay what the seller asks
  • When large aggressive buyers enter → price often rallies

Passive Buyer

  • Bought at the BID price — an aggressive seller sold to them
  • Uses LIMIT orders — lets the price come to them
  • Sits patiently on their bid, doesn't move until filled
  • Often INSTITUTIONS — they step in when price gets cheap and buy everything

Aggressive Seller

  • Sold on the BID — sold to get out or into the market
  • Willing to sell for the price the buyer offers
  • When aggressive sellers enter → price often drops

Passive Seller

  • Sold at the OFFER price — an aggressive buyer bought from them
  • Uses LIMIT orders at specific levels
  • Often institutions — they sell when price gets too high

Key Distinction

  • For EVERY trade: one side is aggressive, one is passive
  • A buying/selling IMBALANCE doesn't have to happen on every trade
  • Aggressive buyers/sellers ≠ imbalances (commonly confused)

How to Read on Footprint

  • Major imbalances arise when aggressive participants enter → visible on footprint
  • Passive buyers/sellers offer support and resistance
  • When market cannot get past a big passive buyer = signal market ready to turn
  • Large numbers on BID at a LOW = passive buyers (institutional support)
  • Large numbers on OFFER at a HIGH = passive sellers (institutional resistance)

Market Movement Rules

  • MARKET ORDERS move the price — limit orders do NOT
  • To push price UP: traders must buy at higher prices
  • To push price DOWN: traders must sell at lower prices
  • Market moves between levels of passive buyers and sellers

Application to Supply & Demand

  • At S&D levels: watch volume when price enters
  • Heavy selling at bottoms / market tops = "hits a wall" and turns
  • Big volume number supporting the market > average number = more reliable
  • These high-reliability setups don't happen daily but are strong when they appear

Aggressive Buyers/Sellers Imbalance vs Aggressive Passive Buyers at Lows

Homework

Explain aggressive vs passive buyer/seller in own words. Are you an aggressive or passive trader?

Key Takeaway for Bot

  • The gold bot reads ASK side for sellers (aggressive sells) and BID side for buyers
  • Large numbers on BID at lows = institutional passive buying = BUY signal
  • Large numbers on ASK at highs = institutional passive selling = SELL signal
  • This is EXACTLY what the 11 gold lessons teach — now with the theoretical framework
  • Bot should distinguish: is this aggressive market order activity or passive limit absorption?
