Calculation

[pichha]

i've tested your arbi bot out, it seems all good but the calculations are off a bit. i will attach screenshot

Its says that it has to make 0.4753% profit on the investment. As you can see i've investment 0.00499408 BTC and i made 0.00495731 BTC, that is -0,73628% not 0,4753% as it calculated.

I have a server in Japan and the ms should be okay. Is it possible that market execution is not the right mode to use, what about limits? Have you think about that?

My settings are default,

Maybe i am doing something wrong?

Thanks for the interest!

I would recommend you run the bot with LOG.LEVEL of "debug" to better understand what happened. fyi the next release will set this log level as the default. This mode would have shown the expected calculation vs. the actual execution step by step.

I definitely recommend having a server with as low latency to the binance exchange as possible. In the example you showed, the total execution took 599 ms which is quite long. The market likely drifted by the time the final trade was executed.

I have had a few conversations about limit orders vs market orders and believe market orders are the best for this use case. That's a lengthy topic, however.

Okay, will do that and send you the log..

what would you suggest about decreasing ms? i have a vps with a good location, what more can i do?

Thank you for reply

Looks like the initial data was 180 ms old. That's important because the first trade (WRXBTC) experienced a market drift.

180 ms might seem small, but keep in mind that in the arbitrage world milliseconds are critical. You and I are competing vs. people with better hardware and better connections working with < 5ms latency.
