<summary>An example of a simple grid</summary>

The grid will place two sell orders and two buy orders, each at a 0.5% increment from the current market price. The order amount will be calculated as 10 divided by the current market price. Orders will be placed at 1-second intervals, with a 60-second gap between each cycle. Sell orders will be placed first.

```json
{
    "execute_price": "ticker()*(1+0.005*order_pos)",
    "execute_volume": "10/ticker()",
    "buy_orders_count": "2",
    "sell_orders_count": "2",
    "time_between_orders": "1",
    "sleep_after_seconds": "60",
    "is_buy_first": "0"
}
```
