Short answer: this feature does not ask you to manually set a "moving range." Instead, when you create a grid, you check a switch called "Trailing Up."
It fixes a common problem with normal grids: after the price breaks above your grid's upper limit, you stop earning. With Trailing Up on, the grid moves up with the price so you can capture a full trend.
Step 1: Find the "Trailing Up" switch when creating a grid
What to do: On the spot or futures grid creation page, find the advanced options and turn on "Trailing Up."
How to do it (App / Website): Go to Trade → Trading Bots → Spot Grid or Futures Grid. After choosing a trading pair, look for "Advanced Settings" or "Advanced (Optional)" in the parameter area — usually below grid quantity and price range. You will see a checkbox labeled "Trailing Up." Check it.
After you check it, the system asks you to enter a "Trailing Up Limit Price." This price decides when the grid stops moving up. For example, if you set the limit price to 50,000 USDT, the grid will no longer move up after the price reaches 50,000.
Completion check: If you see the "Trailing Up" tag in the order confirmation popup and the order details page, the feature is active.
Step 2: Understand how it "trails"
A normal grid stops when the price breaks above the upper limit and stops placing orders. With Trailing Up on, each time the price breaks a "trail step," the whole grid moves up one level.
Specific logic: Suppose your grid upper limit is 45,000 USDT and the step is 4,000 USDT. When the price rises to 49,000 USDT, the system cancels the lowest buy order and places a new buy order at the old upper limit. The whole grid range moves from 25,000–45,000 to 33,000–53,000, following the price upward.
Note: In Trailing Up mode, each grid holds an equal value of the quote currency (for example, USDT), not an equal amount of the coin. This is different from how normal grids calculate positions.
Key limit: Once it is on, you cannot turn it off
Unlike switching from one-way position to hedge mode, this Trailing Up feature cannot be turned off or changed after you check it when creating the grid. It can only stop when the grid ends or when the price hits the limit price.
Also, spot grid Trailing Up currently supports only single-coin grids, not dual-coin grids.
Common failure reason: Limit price set too far or too close
Too close: The price triggers the upper limit too easily, and the grid only trails a couple of steps before stopping. This wastes the feature.
Too far: In theory, trailing far is good, but futures grids have a risk: the notional value of the position may exceed the maximum allowed by your current leverage, which can force the grid to stop.
Risk warning: Chasing a rise is a double-edged sword
Trailing Up lets you capture more in a one-way trending market, but the cost is that your average entry price keeps rising. If the price suddenly reverses and crashes after a high chase, your position cost will be much higher than a normal grid, and losses can be worse.
How to verify it is working
After creating it, go to Trading Bots → Running and find your grid. Tap into the details. If the page shows a "Trailing Up" tag and the "Trail Count" keeps increasing, the feature is working normally.
