Miscellaneous small issues with 0.1.2

[geekasylum]

Just small stuff, that could use a lil polish...
These are from multiple gekkos, on multiple exchanges.

• I tried to change the currencey pairs for BTC-e to: asset = 'USD', currency = 'BTC' since
  I cannot withdraw USD, so my goal is to increase my BTC, with USD simply being the means.

  The following was the result. This was probably meant to give me a nice friendly list of supported pairs.

  /home/gekko/core/exchangeChecker.js:41
  'Gekko only supports the currency/assets pairs [' + exchange.pairs.join('], [
  ^
  TypeError: Cannot call method 'join' of undefined

• O_o ??? There is no config option to set a name

  2014-02-26 20:58:57 (WARN): Warning, trading method has no name

• I shutdown for 1 or 2 minutes to make a config change - missed only 1 or 2 one minute candles
  Possibly nescessary, but annoying, esp as the market turned and I had to manually intervene.
  Surely these last 2 minutes could be retrievd from trade history.

• This gets old real fast. I appreciate the reinvestment, but perhaps when the balance is 0, we don't need to buy?

• Later..
  The minimum seems to be 0.0001, tho Im sure weeks ago I did buy a tiny amount with 8 satoshi via the web interface.

• This line should probably read as follows:
  Note the capital 'W' and extra 'o' - grammatically, the word 'to' != 'too'

  2014-02-26 20:21:10 (INFO): Wanted to buy GHS but the amount is too small (0) at cex.io

• Likewise, capital 'T'

• and 'A'

sorry to dump all these in one issue, but hey, I had to sign up to github to pass them on, so its a trade-off :p

I think grammatical errors can be an easy pull request ;)

The following also occurs with RSI/PPO on some exchanges and not on others (only tested it with my own written ones):
2014-02-26 20:58:57 (WARN): Warning, trading method has no name

[memeyou]

Not really bugs; just user error with the exception of the grammar. If you input bad config values, things will break. Garbage in garbage out.

As for the method with no name its likely due to a missing method in the chosen-exchange's Trader object.

first:

It doesn't really work like that: in your config you can configure a market to trade on. Using trading methods you defined Gekko will trade and hopefully increase your funds. If at the end you want USD instead of BTC you need to either stop Gekko while in a short position (so it's holding USD instead of BTC) or stop it and after that convert to USD.

Though that code should have prompted an error like this one:

Gekko encountered an error and can't continue

Meta debug info:

Gekko version: v0.1.2
Nodejs version: v0.10.0

Error:

Gekko only supports the currency/assets pairs [XRP,LTC], [EUR,LTC], [KRW,LTC], [USD,LTC], [XRP,NMC], [EUR,NMC], [KRW,NMC], [USD,NMC], [LTC,XBT], [NMC,XBT], [XRP,XBT], [XVN,XBT], [EUR,XBT], [KRW,XBT], [USD,XBT], [XRP,XVN], [XRP,EUR], [XVN,EUR], [XRP,KRW], [XRP,USD], [XVN,USD] 

I updated some configuration which resulted in that error. It's working again now.

second:

Also a glitch that came from updates, fixed now. If you use Gekkos built in methods they are named (after the indicator they use), if you write your own trading method you can define your own name.

third:

That's a problem that comes from the fact that exchanges do not provide historical data, something which Gekko needs. If you are unable to run Gekko 24/7 you can also wait for my hosted Gekko solution to come out (at Wizbit), here I'll make sure everything keeps on running all the time.

fourth:

I have the minimum for CEX.io set at 0.000001, if you know what the correct minimum is please let me know!

typos:

I'm not a native english speaker and bad with capitals ;). Fixed the ones you said, if you see more you can also propose a fix for them yourself (by going to the files on github and clicking edit).

[geekasylum]

Thanks for fixing these Mike.
as to my "user error" I was just trying something out. The user error isnt the issue, I suspected the error message was meant to be a bit friendlier (and that was confirmed), and it's been fixed, so that was the entire point.

I'm not using my own trading method. I don't code in node. this is all out-of-the-box.

I know you cant do anything about the history, it was just an 'irk' that I mentioned.

Cex's minimum is a bit hard to nail down. Even their docs dont seem to reflect what the actual API accepts. From gekko's output I'm guessing it's probably 0.0001 as lower values seemed to produce the message. In either case its not really a big thing to worry about.

As for the typos, I wasnt intending to pick on anyone's English, just pointing out some places gekko could be polished to look a little better.

Anyway, The purpose of commenting again on this closed issue was to say Thank You, for implementing these. They were small, but overall they improve the product :)

[askmike]

Yes, I'm always glad if I can do make minor changes and improve the product!

And if you find a better minimum you can still let me know and I'll edit it.
