  • Trader depicted: Ninda SRA (as shown in the video), trading from a bedroom in West London using a laptop connected to US markets.

Mechanism / Causal Chain (As Described in the Video)

Flash-Crash Causal Chain

  1. Mutual fund sell algorithm executes a sale of 75,000 e-mini S&P 500 futures
    • Execution-rate cap: limited to 9% of the previous minute’s trading volume
    • No price floor / no meaningful speed limit: the video describes the behavior as effectively “any price and any speed” so long as the volume cap is respected.
  2. Volume ≠ true buy-side liquidity
    • The video argues trading volume was inflated by HFT activity placing and canceling orders, meaning volume rose without genuine willingness to absorb contracts.
  3. HFT “illusion of liquidity” accelerates the sell-off
    • HFTs traded about 140,000 e-mini contracts (claimed as about 33% of total volume) between 2:41–2:44 p.m.
    • The sell algorithm interpreted the rising volume as increased willingness to buy, creating more sell pressure into insufficient real liquidity.
  4. Cross-market arbitrage transmits dislocations
    • Arbitrage connects derivatives (e-mini) and SPY / S&P 500-related exposure, spreading price dislocations into cash equities.
  5. 2014 study / SEC–CFTC narrative (as framed in the video)
    • Concludes HFTs mainly accelerated issues caused by the mutual fund’s algorithmic execution behavior, rather than acting as the single root cause.

Ninda’s (Alleged) Trading Approach (As Described)

  • Spoofing
    • Place large fake orders, then cancel before execution to manipulate apparent supply/demand.
  • Layering
    • Use multiple fake orders at different price levels to increase the appearance of real demand/supply.
  • Custom HFT bot
    • The video claims he built a custom HFT bot generating many spoofed orders around e-mini S&P 500 futures.
