Request for another example

Hello,

I am having some hard time trying to run a Multi asset, multi exchange live script.

From what I have seen from the code, I understand that asset_no is probably a pointer to asset info as well as the exchange that it refers to.

However, I am a bit confused on how to use this, I would have some intuition to use for example depth(connection/exchange, asset_name) instead of depth(asset_no) (which I am not sure exactly what it is).

So I would be very grateful if you provide some example implementation on how to run a Multi asset, multi exchange live script (even if the second connection is dummy, since we now have only binance futures).

I'm in the process of stabilizing the API, so it hasn't undergone thorough testing yet. But, I will certainly provide more examples. In the meantime, please refer to the following snippet:

let mut hbt = LiveBuilder::new()
    .register("binancefutures", binance_futures)
    .add("binancefutures", "BTCUSDT", 0.1, 0.001) // asset_no: 0
    .add("binancefutures", "ETHUSDT", 0.01, 0.001) // asset_no: 1
    .build()
    .unwrap();

in the algo,

while hbt.elapse(1_000_000_000).unwrap() {
    {
        // BTCUSDT
        let depth = hbt.depth(0);
        let position = hbt.position(0);

        // your algo
    }

    // Due to Rust's borrowing rules, {} is necessary.
    {
        // ETHUSDT
        let depth = hbt.depth(1);
        let position = hbt.position(1);

        // your algo
    }
}

Oh okay, so that would still have worked if we had

let mut hbt = LiveBuilder::new() .register("binancefutures", binance_futures), .register("dummyexchange", exchange_2), .add("binancefutures", "BTCUSDT", 0.1, 0.001) // asset_no: 0 .add("dummyexchange", "ETHUSDT", 0.01, 0.001) // asset_no: 1 .build() .unwrap();

?

Thanks for the answer.

yes, that's the planned usage of the api.

Ok, now I understand. Thanks.
