What?

Asyncio Quant Tick aggregates candlesticks from high frequency tick data from WebSockets.

How?

Sequences of trades that have equal symbol, timestamp, and tick rule are aggregated. Aggregating trades in this way can increase information, as they are either orders of size or stop loss cascades.

As well, the number of messages can be reduced by 30-50%

By filtering aggregated messages, for example only emitting a mesage when an aggregated trade is greater than or equal to a significant_trade_filter, the number of messages can be reduced more.

Example

The following are two sequential aggregated trades by timestamp, nanoseconds, and tick rule.

As it was aggregated from 4 raw trades, the second trade has ticks 4.

[
    {
        "timestamp": 1620000915.31424,
        "price": "57064.01",
        "volume": "566.6479018604",
        "notional": "0.00993004",
        "tickRule": -1,
        "ticks": 1
    },
    {
        "timestamp": 1620000915.885381,
        "price": "57071.2",
        "volume": "9376.6869202914",
        "notional": "0.16429813",
        "tickRule": 1,
        "ticks": 4
    }
]

An example filtered message, emitted because the second aggregated trade exceeds significant_trade_filter >= 1000

Information related to the first trade is aggregated with the second.

[
    {
        "timestamp": 1620000915.885381,
        "price": "57071.2",
        "volume": "9376.6869202914",
        "notional": "0.16429813",
        "tickRule": 1,
        "ticks": 4,
        "high": '57071.2',
        "low": '57064.01',
        "totalBuyVolume": "9376.6869202914",
        "totalVolume": "9943.3348221518",
        "totalBuyNotional": "0.16429813",
        "totalNotional": "0.17422817",
        "totalBuyTicks": 4,
        "totalTicks": 5
    }
]

For 1m, 5m, 15m candles, there is an optional parameter window_seconds.
