Range, levels and amount per level

The fourth step of the wizard sets the whole geometry of the grid in one line. These numbers define the grid step, the profit per cycle and the amount that must be on the account.

What it is

Number	What it means
Lower price	The lower bound of the range; the bot places no orders below it
Upper price	The upper bound; must be strictly greater than the lower one
Level count	How many price levels to place between the bounds, both bounds included. From 2 to 200
Amount per level	How many USDT the bot spends on one order. An optional number; without it — 10 USDT

Important: the amount is for one level, not for the whole grid. The total in the summary is labelled “Total in grid” = amount × level count.

Where it is in the bot

Main menu → 🪜 Grid Bots → ➕ Create Grid Bot → step 4 “Enter range”. On step 5 the amount per level and the leverage can be corrected with the text amount_per_level [leverage]. For a running bot the amount is changed with the 💵 Change order size button, the bounds with 📐 Change boundaries, the level count with 🔢 Change density (see Editing a running bot).

How it works

The line format is lower_price upper_price level_count [amount_per_level], for example 60000 70000 20 6. The separator is a space, the decimal separator is a dot. At this step the range and the level count are not checked yet: the refusal, if there is one, arrives at the confirmation.

On the confirmation screen the bot shows the profit calculator: the range and its width in percent, the level count, the grid step in percent, the amount per level, “Total in grid” and “Est. profit per level cycle: ~… USDT (after fees)”. The step in percent is counted from the lower bound: the width of the range in percent is divided by the number of intervals between levels (levels minus one).

Before the creation the bot checks that the account holds roughly the amount per level × the level count with a 10 % buffer for fees and price swings; on futures this sum is divided by the leverage.

Example with a calculation

The line 60000 70000 20 6:

What	Calculation	Result
Range width	(70,000 − 60,000) / 60,000	16.67 %
Grid step	16.67 % / 19 intervals	≈ 0.88 %
Total in the grid	6 × 20	120 USDT
Required balance, spot	120 × 1.1	132 USDT
Required balance, futures with x2 leverage	120 / 2 × 1.1	66 USDT

The profit of one level cycle is about 0.88 % of 6 USDT, that is roughly 0.05 USDT before fees. If such a step looks too small, widen the range or reduce the level count.

Limits and allowed values

Parameter	Range	Note
Levels	2–200	200 is a hard limit, it cannot be raised
Upper price	strictly greater than the lower one	equal bounds are rejected
Amount per level	greater than zero, not below the exchange minimum	the minimum is the greater of the minimum order value and “price × minimum lot”; on liquid pairs expect 5–6 USDT, the bot names the exact figure in the refusal
Grid step	greater than the double fee	the fee is the real one for your keys
Balance buffer	+10 %	on futures the sum ÷ leverage

Common mistakes and what the bot says

• “❌ Invalid format. Enter: lower_price upper_price levels” — check that there are three or four numbers, separated by spaces, and that fractions use a dot (60000.5, not 60000,5).
• “The number of grid levels must be from 2 to 200 (entered 1).” — a single level is not a grid, 201 and more exceeds the limit.
• “The upper price of the range must be strictly greater than the lower one.” — the numbers are swapped or equal.
• “The amount per level must be greater than zero.”
• “The amount per level (1 USDT) is less than the exchange minimum order (5 USDT). Increase the amount per level.” — the exchange will not accept such a small order.
• “Grid step X % is less than the double fee Y %. Widen the range or reduce the number of levels.” — with such a step every cycle would end in a loss on fees. For example, 200 levels in a range 0.5 % wide give a step of hundredths of a percent.
• “Insufficient balance for the Grid. Required: ~132 USDT (with 10% safety buffer for fees and slippage) for the whole grid, available: 100 USDT. Top up balance or reduce parameters (investment per level/level count/leverage).”
