Hi there, Take a look at the linked image. http://s11.postimg.org/s3v4bamub/Apex.jpg Assume the market had been trading below Point A for a duration of time. Only once the market began trading above Point A ($3), would you be able to place a buy limit order at $3. Assume I place a buy limit order at Point B ($3) once the market reaches the Apex. This has given the market 5 mins to place buy limit orders before mine at $3. Another 5 minutes pass until price reaches my buy limit price at Point C. From the Apex to Point C, this has given the market 5 minutes to place buy limit orders after mine at $3. My order should be ahead/behind 50% of buy limit orders at $3. Correct?
