The proprietary Fib Grid and Range Grid technology first came to mind in 2007 when working for TCA Futures (RIP) in a trading arcade in the City of London – UK’s Wall St. It was conceived in response to a reprimand from the S&P500 desk head trader. He was fuming and publicly criticized me in front of some 120 other traders after hours in the daily retrospective. He’d seen my appalling trade via his CQG trade desk admin module, questioning why I was trading long at the top of the market, one hour out, quite near the end of the session. It was obvious, but I thought, how do you know where the top of the market is? Later that night, I envisioned the Fib Grid and Range Grid to show me. Back then, it was Excel and CQG, and here we are with NinjaTrader from 2009 to 2024. It’s still my core methodology, battle-tested in institutional, hedge fund, and retail trading.

- YSFG – Yearly Session Fib Grid
- MSFG – Monthly Session Fib Grid
- WSFG – Weekly Session Fib Grid
- DSFG – Daily Session Fib Grid
Around 2008/2009, I then worked on the concept of the Fib Grid session breakout, using it to prevent my ludicrous out-of-control scalping. Up to 1200 trade operations in one day was my record, plus burnout after TCA Futures as a privateer with MFGlobal. It made my broker rich and me a 35% account loss – Emini ES trading, not small change, it hurt badly. So I stopped and later was reborn as a day/swing trader, making 1 to 3 trades per day on the DSFG. This method is used in the ATS Discord groups as a core method to teach good habits and run the trades. Fib Grid made me and saved me, thank you to the head trader.
Note: From 2015, when I traded for managed futures/futures hedge funds, I used WSFG breakouts and MSG breakouts and let that go for several weeks/months. You could get up to 100K per lot sometimes on NQ or ES FDAX, etc. So some quite serious trades have gone down, and a good lot of time too. https://algotradingsystems.net/About I guess I could follow tradition and call it the Leeson lines after my surname, as some did and still do, but to me, FibGrid has more meaning.
