You shouldn't you just in the cell place =bittrexGetbalances and it should go out and download all your balances? Is there more to it. Please let me understand when i do this I get
Error
Unknown range name: 'BITTREXGETBALANCES'

ok so looks like
=bittrexGetbalances()
and
=bittrexGetOrderHistoryV1()

is all that working for this script am I correct. Sorry I am learning

@leejie8008 looks like it pulls everything you have a wallet on BTW

Thanks. Pretty helpful

None of you unfortunately answered, how the sheet itself can be generated? I added the keys to key sheet, but don't get any results being displayed. Please help!

Hey could somebody clarify how I would send a buy order with this code?
Ive tried:
bittrexPrivateRequest("Buy",)
but I do not know what to insert in the field "Payload".
I am aware that i have to insert the currency, the amount and the rate; but do not know in which format
Many thanks!
