Invalid order signature

[GoldRat]

I've tested my algorithm by example you've given at #26. The result is perfect match to your r, s, v values. However the error "Invalid order signature" still appears (not always but sometimes). As well as "Invalid cancel signature"

Is there any error in prodiced payload for this wallet, key and parameters?

Hi!
When i use the payload with your address, Idex answer "try making a larger order..."
{"tokenBuy":"0xcdcfc0f66c522fd086a1b725ea3c0eeb9f9e8814","amountBuy":"139611895000864697098","tokenSell":"0x0000000000000000000000000000000000000000","amountSell":"40000000000000000","address":"0x351296f44a5bf3f05eaa7d78a560f50dd736b728","nonce":"2","expires":"10000","r":"0x50573d44812198c38d03fc815026c8c85669a43bcade519f44440acaaf2ab2be","s":"0x3136be5df241628bcafb845aea2c9b4d6e5d1bb87bc410af228e4d503ec39134","v":28}

But, when i change your address field to my 0x8F8E5665D94B4EaD9978247bA0E9d643be1936f4 ,i get the Invalid order signature, allthough i use Node.js algorihm from API samples.

Maybe do you know the reason?

I think, that "Invalid order signature" means "Any error"

You should calculate r, s, v using your address and keys I guess.
