How to choose a pair for a grid bot

1. Liquidity

The bot places all-or-nothing orders. On a pair with heavy turnover and a deep order book they nearly always fill. On a little-known coin the price can touch the level while the order does not fill: the book lacked the volume.

2. Swings

A grid trades when the price moves back and forth. A pair that stands still for weeks gives few trades. A pair that moves tens of percent a day runs down the whole grid fast and leaves you holding the coin.

The grid’s step is chosen to match the pair’s usual movement. A step far smaller than that gives many trades whose result goes to fees. A step far larger leaves the bot waiting for its level for weeks.

3. Would you hold it

This is the main one. In a fall a grid buys and waits. If the price does not come back, you are left with a coin bought above the market. On a pair you would hold anyway, that is unpleasant. On a coin you know nothing about, it is a loss.

4. The minimum order

Each pair has a minimum order size set by the exchange. A rung’s amount must be above it, with room to spare. The app shows the minimum for the chosen pair right in the bot form.

Checking your choice

• Run a backtest on the pair over several different periods.
• Keep the bot on paper for at least a week.
• Compare two pairs with the same settings — over the same dates.
