Resulting from the following discussion Combo Bot Lines Twice as Far Apart

Currently `Combo Bot Minigrids`

only offer an arithmetic spacing resulting in different deviations and required changes per `Grid step`

.

`Grid Bots`

already offer a geometric grid spacing. The same can also be achieved for `Combo Bots`

. And there are other ways where e.g. the spacing per minigrid can be geometric even though the deviations can differ from minigrid to minigrid.

A possible solution is here:

The relative spacing can be equal within a Minigrid by calculating the required change `r`

per grid step it via the

`(n + 1)-th root of (range-high / range-low)`

, where`n`

is the number of grid lines, i.e.

`r = (h / l) ^ (1 / (n + 1))`

and transferring the resulting percent change factors to the current `price range`

.

## Example

Price range

`[100, 150]`

`5`

Minigrid levels

#### Required change per grid step

`r = (150 / 100) ^ (1 / (5 + 1))`

`= (3 / 2) ^ (1 / 6)`

`~ 1.0699`

`= +6.99%`

#### Deviation per grid step

`d = 1 / r`

`d = 1 / 1.0699`

`= 0.9347`

`= -6.53%`

#### Resulting grid level prices

`p(i) = l * r ^ i`

for`i = 0, ..., 6`

`100 * 1.0699 ^ 0 = 100.00`

`100 * 1.0699 ^ 1 = 106.99`

`100 * 1.0699 ^ 2 = 114.47`

`100 * 1.0699 ^ 3 = 122.47`

`100 * 1.0699 ^ 4 = 131.04`

`100 * 1.0699 ^ 5 = 140.20`

`100 * 1.0699 ^ 6 = 150.00`

## What else could be achieved with that?

### Equally geometrically spaced DCA Minigrids?

Yes, as I have shown in my `Trading math formulas`

the DCA steps can be scaled geometrically using `Orders step`

and `Step scale (beta)`

. Only `Step scale (beta)`

would have to be calculated for that based on the first DCA Minigrid.

### Configurable equally geometrically spaced DCA Minigrids?

Yes, now `Orders step`

and `Step scale (beta)`

would have to be calculated for that based on the not yet configurable `Grid step %`

and the number of `DCA Minigrid levels`

.

### All Minigrids with equal geometrically spaced Minigrids?

Yes, now `Orders step`

and `Step scale (beta)`

of the DCA Minigrids would have to be calculated based on the configuration of the `Base Mingrid`

’s `Top price %`

and the number of `Base Minigrid levels`

, i.e. the resulting `Grid step %`

, and the number of `DCA Minigrid levels`

.

### Configurable equally geometrically spaced base and DCA Minigrids?

Yes, now `Top Price %`

of `Base Minigrid`

would have to be calculated base on the not yet configurable overall `Grid step %`

and the number of `Base Minigrid levels`

and for the `DCA Minigrid`

s the value of `Orders step`

and `Step scale (beta)`

on the configured overall `Grid step %`

and the number of `DCA Minigrid levels`

.

### Summary

If a geometric grid spacing would be available, we would be able to configure geometrically spaced `Base`

and `DCA Minigrids`

where

- each
`Minigrid`

uses its own consistent geometrical spacing - each
`DCA Minigrid`

uses the same geometrical spacing as the other`DCA Minigrids`

- all
`Minigrids`

share the same consistent geometrical spacing

And in the best case the `Grid step %`

is directly configurable for `Base`

and `DCA Minigrids`

.

`Orders step`

and `Step scale (beta)`

could be calculated using “my” formulas or in the best case even that be integrated.
