USD/CHF has been declining since the start of 2022. It lost as much as 16,000 pips, and today it updated the yearly low, opening a chance for an upward movement.
So, starting from the current prices, place a grid of buy limits at an increment of 500 pips. After accumulating long positions, exit the market with a take-profit order upon a breakdown of 0.8550 or after a movement from the first order.
This grid trading method, usually used on cross rates, involves significant time and distance holding of positions. As such, market players should use swap-free accounts, not increasing the volumes in the grid (0.01 standard lot for every $1,000 of the deposit), and monitoring price movements that could be as much as 6,000 pips.
Good luck in trading and don't forget to control the risks! Have a nice day.
