If you create a buy order and type in a higher price than the lowest selling offer your BTC balance will be reduced using the price you typed in, not the one from the lowest sell orders.

I created an order to buy 1000 FIMK with 0.0001 price and my balance was reduced by 0.1BTC, though the lowest sell order was with the price 0.00000085 for >4000FIMKs.

Be careful.

As it could be seen, I bought 1000FIMK for 0.1BTC.
I recommend to check your transaction history on CCEDK if you made any buyings/sellings there.

Related to this, the min/max price calculator went bezerk and and cancelled all the buy orders. I tried to contact CCEDK and Ronny in every possible way (except knocking on the door), but didn't get any answer...

This reminds me of the problem, that FIMK still isn't listed in any proper exchange, that wouldn't mess up the orders and fuck up the price range (excuse me French, but I'm getting tired of these buggy platforms).

Some weeks ago, I made an application to Poloniex, but haven't got any answer. Anybody know, how to get listed in Polo or any of the well known, big and reliable players in the field?

All the buy orders on CCEDK have been removed. Disappointing.

Sounds to me like  lucrative business opportunity! :)

The most important thing in Poloniex & Co is that they have been (maybe even tested before) running in production for years with thousands of customers. That's why I applied. Anybody know, how to find out why the application hasn't been accepted?

Yes, we've seen those strange offshoots there previously.

Fitcoin is coming to the rescue, in next 48 hours we're deploying Lompsa based interface where the BTC asset on the FIMK AE can be traded as BTC/FIMK pricing just like every crypto does.

Currently more reliable pricing for FIMK can be seen here: https://lompsa.com/#/assets/fim/2339799191405258101/trade

Process the price 1/x (divide 1 by the price) and you get directly the FIMK value in BTC. 1 500 000 FIMK/BTC means 0.00000067 BTC/FIMK.

Ye, that's because I typed a high price in buy order.
And it looks like even for last 24 hours I wasn't the only one who did that (and billed wrong as well I guess).

Yep. Ccedk is a shitty exchange. I have reported them abot this  over a year ago ut they just cant get it to work:

Ticket #9323797: bug in trading platform?
Created by: *******(*****@***)
Company: Individuals
Queue: Tech support
Priority: normal
Ticket Description: Im not sure but I think there is a bug in your trading system. I made an buy order for fimk/btc in 02.02.2015 14:54 with price of 92 satoshis per fimk. However after that there is several actual tradings (02.02.2015 20:52 ) for price of 90 satoshis (which is less than my 92), but my order havent treated. In that case I didnt got fimks that I wanted and also the seller of actual trade got only 90 satoshis per fimk although he/she could have got 92 (that is roughly 2.2% inferior price). Im not sure if that is purposed but in general all the exchanges (in crypto world and in stock market) fulfills THE BEST POSSIBLE PRICES for their customers. If that is rather purposed behaviour than a bug I as a customer humbly ask you to change this. That is kind of weird behaviour and leaves traders unsatisfied. Thank you.

| Hello, ****** *******. My name is Ivan and I'm one of developers. About your issue:
| At this case, we didn't see any bugs. I checked your transactions logs. You maked order for price 92, and get complete trades for exactly this price. System using counter-trade algorithm to satisfy all of client's order prices.
| But, we respect opinions and wishes of all of our clients, so, in the night I personally researched another exchanges for this questions and can agree with You. I can promise, that this system will be rebuild for best meeting client's wishes, and we will integrate it into our exchange asap. This question already in working.
| Best Regards, Ivan.
| Technical Support Dep.

Its true that my order finished for that price but not in the right time. (it should be completed immediately when someone offers lower price. Anyway they does not consider it as a bug which it obviously is. Sorry for your lose. 0.1BTC for 1000FIMK is such a crappy deal.

Probably it works the same way for selling to. You see buy orders from 30 to 100 sat, create a sell order to cover all of them, type in 30sat or less and receive total amount of BTC calculated with price you typed (not a sum of all orders executed with correspondive prices).
I'm sure it has happened on 11.04:

Someone, who sold FIMK on that day and typed in the price 0.00000013 should check his BTC balance.

So you are saying you can game their system?
Have you tried it? It's the fastest way to know if that's the case.

Sure would be a fun fact to know.

That would sure help them to fix their system.

But always be honest  8) especially to those who've supported FIMK from the start.

It's a gaming where CCEDK wins.
You want to sell 1,000,000 FIMK for 100sat (lets say there is a corrersponding BUY offer).
Type in the price of 10sat.
And receive 0.1BTC for your million. (and CCEDK internal balance will be increased by 0.9 BTC).

I don't want to try it so there will be a clean picture for them in my account to compensate their errors.

Actually I don't know where these exceedings and shortages exactly go - to the CCEDK balance or to the ones, whose orders were fullfilled.
I mean maybe that imaginary guy with BUY order of 1,000,000 for 100sat will sell them only for 0.1BTC in described case above.
But in that case he will profit from any mistypes of the sellers (or sellers who expect the normal logic from exchange (if CCEDK thinks such logic is NORMAL as you might think from APA post)).
