Explain about allOrders and myTrades in spot

I don’t understand why binance don’t explain all Quests.
So I use /api/v3/myTrades and /api/v3/allOrders to find how I spend in trade with fee.
in the first I use /api/v3/allOrders and give result like that:

[{

        "symbol": "BTTCUSDT",

        "orderId": *****,

        "orderListId": -1,

        "clientOrderId": "******",

        "price": "0.00000000",

        "origQty": "30588846.0",

        "executedQty": "30588846.0",

        "cummulativeQuoteQty": "54.44814588",

        "status": "FILLED",

        "timeInForce": "GTC",

        "type": "MARKET",

        "side": "BUY",

        "stopPrice": "0.00000000",

        "icebergQty": "0.0",

        "time": 1647099489614,

        "updateTime": 1647099489614,

        "isWorking": true,

        "origQuoteOrderQty": "54.44814600"

    },
     {
        "symbol": "BTTCUSDT",
        "orderId": ****,
        "orderListId": -1,
        "clientOrderId": "******",
        "price": "0.00000000",
        "origQty": "30558257.0",
        "executedQty": "30558257.0",
        "cummulativeQuoteQty": "54.08811489",
        "status": "FILLED",
        "timeInForce": "GTC",
        "type": "MARKET",
        "side": "SELL",
        "stopPrice": "0.00000000",
        "icebergQty": "0.0",
        "time": 1647099561989,
        "updateTime": 1647099561989,
        "isWorking": true,
        "origQuoteOrderQty": "0.00000000"
    },]

So I thing
‘executedQty’ is QTY BTTC after exchange take fee?
‘cummulativeQuoteQty’ is amount USDT after exchange take fee?
This method not help me to know how I spend USDT first include exchange fee.

I try another method: /api/v3/myTrades

    [{

        "symbol": "BTTCUSDT",

        "id": ****,

        "orderId": ****,

        "orderListId": -1,

        "price": "0.00000178",

        "qty": "30588846.0",

        "quoteQty": "54.44814588",

        "commission": "30588.8",

        "commissionAsset": "BTTC",

        "time": 1647099489614,

        "isBuyer": true,

        "isMaker": false,

        "isBestMatch": true

    },

    {

        "symbol": "BTTCUSDT",

        "id": ****,

        "orderId": ****,

        "orderListId": -1,

        "price": "0.00000177",

        "qty": "30558257.0",

        "quoteQty": "54.08811489",

        "commission": "0.05408811",

        "commissionAsset": "USDT",

        "time": 1647099561989,

        "isBuyer": false,

        "isMaker": false,

        "isBestMatch": true

    }]

‘qty’ is QTY BTTC after exchange take fee?
‘quoteQty’ the total amount USDT I spend without exclude any fee because the fee take from ‘qty’ BTTC
I don’t understand in this array

{

        "symbol": "BTTCUSDT",

        "id": ****,

        "orderId": ****,

        "orderListId": -1,

        "price": "0.00000178",

        "qty": "30588846.0",

        "quoteQty": "54.44814588",

        "commission": "30588.8",

        "commissionAsset": "BTTC",

        "time": 1647099489614,

        "isBuyer": true,

        "isMaker": false,

        "isBestMatch": true

    }

exchange take fee from BTTC and commission is 30588.8 this mean: “qty”: “30588846.0” + “commission”: “30588.8” to get the total BTTC purchase without exclude fee?

In this array:

‘quoteQty’ is amount USDT after exchange take fee?
‘qty’ the total QTY without exclude any fee because the fee take from ‘quoteQty’ USDT?

{

        "symbol": "BTTCUSDT",

        "id": ****,

        "orderId": ****,

        "orderListId": -1,

        "price": "0.00000177",

        "qty": "30558257.0",

        "quoteQty": "54.08811489",

        "commission": "0.05408811",

        "commissionAsset": "USDT",

        "time": 1647099561989,

        "isBuyer": false,

        "isMaker": false,

        "isBestMatch": true

    }

exchange take fee from USDT and commission is 0.05408811 this mean: “quoteQty”: “54.08811489” + “commission”: “0.05408811” to get the total USDT spend to purchase without exclude fee?
ALL my things in true or false?

so in this trade record,

the qty is for how many BTTC is traded with price of 0.00000177. It didn’t the trading fee, which means the qty is just saying how many BTTC is traded with USDT.

In this trade, the commission fee (trading fee) is $0.05408811 in USDT.
