Position sizing matters, and you need to know when to kill these systems.
I’ve tested grid setups on demo accounts - they work fine in normal markets. But when news drops or central banks make announcements? They get dangerous fast.
Too many traders set them up and forget about them, expecting easy passive income. That’s how you blow accounts.
Watch your economic calendar and shut down grids before big news hits. Good traders don’t treat grids any differently - they monitor them like everything else.
Grid trading works fine when markets move sideways, but trends will wreck you. The profits look great until one big move hits and your losses spiral out of control. I’ve watched traders crush it for months, then blow up their accounts in a single trend day. Position sizing is everything - go too big and you’re toast. If you’re gonna try grids, risk max 2-3% of your account. Don’t keep adding to losers past your limit. The traders who actually make money with grids? They babysit their systems when the market starts moving hard.
Grid systems work until they don’t. I ran some automated ones in 2019 - they printed money for 6 months straight.
Then Brexit hit and GBP started trending hard. Lost 40% in two days because the grid kept doubling down against the move.
These systems think markets always reverse. When you get real breakouts or major news, they just keep adding losing positions.
I know someone who’s manually traded EURUSD grids for 3 years. He uses tight ranges and kills the system when trends get strong. Takes serious discipline to know when to bail.
Backtests look incredible because they test on ranging markets. Real trading includes those brutal trending periods that destroy grids.
