Not enough XXX available to offer.

[rnevet]

I'm seeing several errors like this one, I'm not sure if this is because of recent logic changes. Running on develop branch, but I think they also happen on master.

Example:

2016-12-22 16:27:14 Error: Not enough FCT available to offer. Requesting createLoanOffer 2016-12-22 16:27:14 Placing 2.07942785 FCT at 0.019899% for 2 days... Loan order placed. 2016-12-22 16:27:13 Placing 1.03971393 FCT at 0.019799% for 2 days... Loan order placed.

I'm seeing the similar behaviour on master, I'm on commit 7e799cef39e3e1751e14cf77b9ae6a155f887fc5

Log isn't exactly the same, I have this backtrace though:

@laxdog, this is the same issue, logs have been changed in develop branch.

[laxdog]

OK, cheers. Trying to recreate it now. Any idea what's triggering it?

[laxdog]

@rnevet it looks like when you are doing a spread lend that it doesn't take into account the minimum you can lend. So sometimes when you get to the last spread_step, the amount left to loan is too low.

There's actually a TODO in Lending.py about it:

--> 180     step_pct = (gap_top - gap_bottom) / spread_lend
    181     # TODO check for minimum lendable amount, and try to decrease the spread.
    182     # e.g. at the moment balances lower than 0.001 won't be lent
    183     # in case of empty lendbook, lend at max

@rnevet @laxdog I have created a potential fix in #166, please test it if you have an opportunity to. It is based off master.

[laxdog]

Been running it for the last 4 hours without seeing anything. I'll leave it overnight and get back to you.

[laxdog]

@Evanito I accidentally closed the window with the log in it, but I don't think the patch has solved it. I had two instances of "Not enough BTC" blah blah, overnight.

I've kicked it off again to try and get you the backtrace, but I think it's just in the same place as last time.

Here we go:

I've found putting the spreadlend up to 20 increases the chances of it happening, so you can try that if you're testing.

[Evanito]

Reopened until we can confirm previous commit fixed problem, it was merged because it is an improvement in logic that we should include whether or not it resolves this specific issue.

[laxdog]

Agreed, the code you put in is correct and an improvement. It just doesn't resolve this issue.

[Evanito]

This error was due to splitting a satoshi in half, and they both wanted to round up. Fixed in lending-rewrite branch.

[utdrmac]

Would this solve this recent issue I'm experiencing? Was away from home all weekend, but left bot running. Came home to bunches of errors like this:

Error: Amount must be at least 0.01. Requesting createLoanOffer

[Evanito]

@utdrmac It is a different error but yes, #174 fixes it.
