That's a bug! Binance has a peculiar way of handling arrays in requests - I'll push a fix shortly. Thanks for reporting it!

Hi @jamesbayly - merged via #508

Should be on npm shortly, as of version v2.15.6. Thanks again for reporting it - let me know if you notice any other issues.

[jamesbayly]

Thanks for the quick fix, tested and confirmed!

Hi @tiagosiebler I believe you've created another bug during this fix:

getRollingWindowTicker(params) {
        if (params && params['symbols'] && Array.isArray(params['symbols'])) {
            const symbolsQueryParam = JSON.stringify(params.symbols);
            return this.get('api/v3/ticker?symbols=' + symbolsQueryParam);
        }
        return this.get('api/v3/ticker', params);
    }

if I include symbols then you discard the other params provided (including windowSize?: string and type?: 'FULL' | 'MINI')

Hi @tiagosiebler I believe you've created another bug during this fix:

That was a silly mistake, and a reminder for me to be more careful when multitasking. Apologies, fix incoming via #511 - should be on npm shortly as of v2.15.7. Thank you for pointing it out.
