Base step size

API Spot/Margin API
1

Ok maybe I don’t understand the concept, not sure.

Using the data from /api/v3/exchangeInfo I tried to figure out how to get the base asset step size. Lets say I want to trade ILV/USDT as market, I know the step size if I want to sell ILV, which is LOT_SIZE => stepSize => 0.00100000. But I can’t find the step size for USDT (when buying,) it should be 0.00010000, which differs. So what’s the correct way of finding the quantity step sizes for both buy and sell in market orders?

Here is the filters for ILVUSDT


"filters": [
                {
                    "filterType": "PRICE_FILTER",
                    "minPrice": "0.10000000",
                    "maxPrice": "100000.00000000",
                    "tickSize": "0.10000000"
                },
                {
                    "filterType": "PERCENT_PRICE",
                    "multiplierUp": "5",
                    "multiplierDown": "0.2",
                    "avgPriceMins": 5
                },
                {
                    "filterType": "LOT_SIZE",
                    "minQty": "0.00100000",
                    "maxQty": "922327.00000000",
                    "stepSize": "0.00100000"
                },
                {
                    "filterType": "MIN_NOTIONAL",
                    "minNotional": "10.00000000",
                    "applyToMarket": true,
                    "avgPriceMins": 5
                },
                {
                    "filterType": "ICEBERG_PARTS",
                    "limit": 10
                },
                {
                    "filterType": "MARKET_LOT_SIZE",
                    "minQty": "0.00000000",
                    "maxQty": "193.93607366",
                    "stepSize": "0.00000000"
                },
                {
                    "filterType": "TRAILING_DELTA",
                    "minTrailingAboveDelta": 10,
                    "maxTrailingAboveDelta": 2000,
                    "minTrailingBelowDelta": 10,
                    "maxTrailingBelowDelta": 2000
                },
                {
                    "filterType": "MAX_NUM_ORDERS",
                    "maxNumOrders": 200
                },
                {
                    "filterType": "MAX_NUM_ALGO_ORDERS",
                    "maxNumAlgoOrders": 5
                }
            ]

For ILV, check the LOT_SIZE, so should check the stepSize ( 0.001)
For USDT, check PRICE_FILTER, so the price should has tick size of 0.1.
