## The main features of Multi-limit mode.

**Multi-limit **is a method of placing orders in the spot market that allows users to create order grids by setting a price range, the number of orders in the grid, and a choice between geometric or arithmetic progression to generate order prices within a specified grid range.

By using the new Multi-limit tool, users can improve their trading experience and automate their strategies. In this article, we will take a closer look at this tool, explaining each aspect of it in plain language.

**The main features of Multi-limit mode include:**

- Setting the upper and lower price range for orders in the grid, as well as the investment amount;
- Automatic calculation of the price of each grid order, depending on the selected price range and the selected mode (arithmetic or geometric);
- Possibility to create grids containing up to 15 orders;
- Preview of the order grid before placing it.

After confirmation, each limit order created within the Multi-limit grid will be displayed in the Open Orders section in the lower section of the trading terminal, near Trade History.

## Arithmetic progression mode.

Arithmetic progression provides traders with the ability to create orders with constant price increments between them. This is especially useful when an equal distribution of orders within a given price range is required.

Let's look at an example of a grid to buy BTC on the BTC_USDT market with a price range of 27299 to 24799 and an Invest Amount of 800 USDT:

*You want to place 5 orders in this range with equal interval between them, and you have 800 USDT to invest.**You select the arithmetic progression mode and specify the starting price (27299), the ending price (24799), the number of orders (5) and the amount to be invested (800 USDT).*

The system will automatically calculate the price of each order, taking into account the arithmetic progression, and place them as follows:

- Order price 26799, investment: 160 USDT
- Order price 26299, investment: 160 USDT (decrease by 500 compared to the previous one)
- Order price 25799, investment: 160 USDT (decrease by 500 compared to the previous one)
- Order price 25299, investment: 160 USDT (decrease by 500 compared to the previous one)
- Order price 24799, investment: 160 USDT (decrease by 500 compared to the previous one)

Thus, using arithmetic progression, you create an even grid of orders to buy BTC in the specified price range on the BTC_USDT market, while investing the entire available amount of 800 USDT. This provides a more flexible and controlled approach to your trading strategy given the specified investment amount.

## Geometric progression mode with uniform distribution of the sum.

Geometric progression provides traders with the ability to create orders with price changes in geometric progression, with the amount per order distributed equally. Let's look at an example of a grid to buy BTC on the BTC_USDT market with a price range of 27299 to 24799 and an investment amount of 800 USDT:

*You want to place 5 orders in this range with exponential price change and equally distributed amount.*-
*You select the geometric progression mode and specify the top price of the range (27299), the bottom price of the range (24799), the number of orders (5) and the investment amount (800 USDT).*

The system will automatically calculate the price of each order using geometric progression and distribute the investment amount evenly between them.

To evenly distribute the amount (800 USDT) to each order, we can use geometric progression. Let each order be with the same amount and with the ratio of prices in geometric progression (R):

(we count prices in the examples taking into account 2 decimal places, which may slightly affect the accuracy of price calculations).

**R** - coefficient

**n** - number of orders

**Pn** - order price

**R** = (hight_price/low_price) ^ (1/n)

**R** = (27299 / 24799) ^ (1/5) = 1.01939

Now, using this R value, we can calculate the prices of each order according to a geometric progression:

**Pn** = low_price*R ^ (n-1)

**P1** = 24799 * 1.01939 ^ (1-1) = 24799

**P2** = 24799 * 1.01939 ^ (2-1) = 25279.85

**P3** = 24799 * 1.01939 ^ (3-1) = 25770.02

**P4** = 24799 * 1.01939 ^ (4-1) = 26269.70

**P5** = 24799 * 1.01939 ^ (5-1) = 26779.07

1. Order price 26779.07 USDT, investment: 160 USDT

2. Order price 26269.70 USDT, investment: 160 USDT

3. Order price 25770.02 USDT, investment: 160 USDT

4. Order price 25279.85 USDT, investment: 160 USDT

5. Order price 24799 USDT, investment: 160 USDT

Now we have a grid of 5 orders to buy BTC in the specified price range on the BTC_USDT market, with each order having the same investment amount of 160 USDT. This method ensures order distribution closer to the last price and earlier buy/sell than arithmetic mode.

## Let's compare arithmetic and geometric progression.

Arithmetic | Geometric | Volume | |

1 | 24799 | 24799 | 160 |

2 | 25299 | 25279.85 | 160 |

3 | 25799 | 25770.02 | 160 |

4 | 26299 | 26269.70 | 160 |

5 | 26799 | 26779.07 | 160 |

Avg | 25799 | 25779,52 |

According to the average price of generated orders, we observe that with geometric progression the average price of all orders tends to the lower limit (the difference is more noticeable when the number of orders increases). This means that we implement most of the investment amount earlier at the same price change in the market.
