Grid Trading on Aster

• A grid bot automates one simple idea: buy low, sell high, over and over.
• You pick a price range and split it into rungs (grids).
• The bot places a limit order at every rung — buys below the current price, sells above it.
• Each time price ticks down to a rung and back up to the next, it books the spread as profit.
• It never sleeps: while the market chops sideways, it keeps harvesting the oscillations.

Aster supports three grids so you can match different market conditions. The difference is whether the bot starts with a position, and which way it leans.

• Neutral grid. Starts with no position and only opens when price crosses the nearest rung; profits from swings in both directions. Best for a sideways / ranging market.
• Long grid. Leans bullish — accumulates on dips and biases toward holding a long. Use it when you are mildly bullish and expect a choppy uptrend.
• Short grid. Leans bearish — sells into bounces and biases toward holding a short. Use it when you are mildly bearish and expect a choppy downtrend.

In manual mode you set four numbers yourself; in auto mode Aster computes them from recent volatility and you fine-tune.

• Upper / Lower price. The top and bottom of the range the grid works in.
• Grid number. How many rungs the range is split into; more rungs = thinner profit per grid but more frequent fills.
• Initial Margin + leverage. The capital you commit and its multiplier. More leverage = more liquidation risk — see below.

How auto mode picks the range and rung count: the range follows Bollinger bands (a moving average ± a multiple of the standard deviation), and the rung count comes from the symbol's Average True Range (ATR) over recent hours.

Upper band = MA + bbm × StdDev
Lower band = MA − bbm × StdDev
Grid count ≈ (Upper − Lower) ÷ ATR(recent hours)

• On start, the number of limit orders placed = grid number + 1: sell orders above the price, buy orders below it.
• When a buy fills, the bot immediately places the matching sell one rung above (and vice-versa) — the profit is that buy↔sell spread.
• Trigger: the grid can start immediately, or wait until price reaches a trigger price.
• A maximum of 10 active or pending grid strategies per account.
• Every grid order is a limit order — you are generally on the maker side, adding liquidity to the book.

• Wins: choppy / ranging markets where price oscillates inside your band. The more it swings, the more it harvests.
• Loses: a strong one-way trend that runs through the range — if price breaks below your lower bound, you are left holding positions on the wrong side.

Liquidations run off the oracle mark price — to understand how your position is priced and liquidated, see the Oracle.
