SpyGate Detection Table: April 21st, 2021

SpyGate ended the day Wednesday with 134 program trades detected, about the same as Tuesday. A moderate program day. There were more buys than sells but the sells were bigger in size. The day ended with a small $143M more buys than sells on a day that traded $17B in detected programs.

A small early sell program fired at 9:40:00 ET post opening. The markets bought into that sell program and fired two buy programs at 10:07 and 11:55:20 to establish the morning direction. The buy programs concluded all the bot trades detected before the Final-2. The bot-less period between noon and 15:30 was mostly directionless chop. The wake-up bot at 15:30 brought in volume and the tape was off to the races.
Price Action During Program Trades

The fight for the close was dominated by early buy programs starting at 15:30 into the market on close imbalance release at 15:50. At that point Buy and Sell bots traded against each other into the close.

What is an STTProgram trade?
SpyGate detects several different types of programs trades. An STT program is a simultaneous triggered trade. The detector looks for a basket of symbols trading at the same time. The price action around these detected trades helps us deduce if the program was a buy or a sell. Our detector reports the number of symbols in the trade, the number of individual trades executed, and the dollar amount of those trades.
What is SpyGate?
SpyGate is a proprietary tape reader that analyzes price action on all the exchanges and sniffs out unusual trades. The detector follows price action and accumulates adaptive knowledge using Machine Learning (ML) and Artificial Intelligence (AI) to recognize algorithms and program trades as they execute. The first implementation detects STT Programs ( Simulatanousely Triggered Trades). These basket trades execute thousands of transactions in miliseconds. The transactions are in millions of dollars. This product is under heavy development and is currently available free for our traders in our TradeChat trading room along with the MiM and live breaking news.
