In early 1986 Steidlmayer and Kevin Koy started Market Logic School to teach profile trading. Around the same time the CBOT gave up on marketing the Liquidity Data Bank directly to the public (CISCO Futures became their vendor). Public access to tick data increased greatly so that profiles could be constructed real-time intra-day (whereas the LDB data breaking out the category of participant at price was still generated at the end of day).
