Arithmetic and Geometric modes

The grid mode defines how the levels are spread between the bounds: with the same distance in money or with the same distance in percent.

What it is

Mode	Button in the wizard	How the levels are placed	In the bot card
Arithmetic	📐 Arithmetic (uniform)	The step between neighbouring levels is the same in USDT	“📏 Mode: Arithmetic”
Geometric	📈 Geometric (percentage)	Each next level is higher than the previous one by the same percent	“📏 Mode: Geometric”

In an arithmetic grid the step in percent is larger at the bottom of the range than at the top: 600 USDT from 60,000 is 1 %, but from 65,400 it is already 0.92 %. In a geometric grid the percent is the same at every level, but the step in money grows from the bottom upwards.

Where it is in the bot

Main menu → 🪜 Grid Bots → ➕ Create Grid Bot → step 5 “Choose mode and enter parameters”. The mode is chosen at creation; it is not among the editing buttons of a running bot — to change the mode, create a new bot.

How it works

• A narrow range (a few percent) — the difference between the modes is barely noticeable, either one will do.
• A wide range (tens of percent and more) — in an arithmetic grid the levels near the upper bound give a noticeably smaller profit per cycle in percent than the ones near the lower bound. Geometric evens out the profit per cycle in percent across the whole grid.
• The line “Grid step: ~X %” on the confirmation screen is an estimate counted from the lower bound, so it is approximate for both modes. The exact level prices are visible in the bot card and in the orders on the exchange.
• Trailing-Down on futures appends levels downward geometrically, keeping the same grid density (see Trailing and Trailing-Down).

Example with a calculation

Range 60,000 — 66,000 USDT, 11 levels (10 intervals).

	Arithmetic	Geometric
Step	600 USDT everywhere	≈ 0.96 % everywhere
Levels	60,000, 60,600, 61,200 … 66,000	60,000, 60,575, 61,155 … 66,000
First interval	600 USDT = 1.00 %	≈ 575 USDT = 0.96 %
Last interval	600 USDT = 0.92 %	≈ 626 USDT = 0.96 %

With 10 USDT per level, a cycle on the lowest level of the arithmetic grid brings about 0.10 USDT before fees, on the highest one about 0.09 USDT; in the geometric grid every cycle gives about 0.096 USDT. Over such a range the difference is pennies; it becomes significant when the upper bound is one and a half to two times the lower one.
