  Add own datapoints to graph
Posted by: Joris tsja - 01-09-2018, 12:54 PM - Forum: Feature Requests - No Replies

It could be handy if you could say in your strategy add point to graph like you do with short and long but in different color. 
also add other data to the graph so you can see  moving avr or other data set on the graph.


  Is the papertrader accurate?
Posted by: redquicksilver - 01-09-2018, 06:41 AM - Forum: General Discussion - Replies (1)

Please could you help me understand how the paper trader gets it's buy and sell figures as I fail to see the comparison to the figures it produces and real live data from the exchange I am using, for instance:

A paper trader running last night for EUR-ETH on GDAX gives:

2018-01-09 02:36       2018-01-09 05:33       3 hours            947.404            957.339         9.94              1.05%


However looking at GDAX and the closing price for those times shows:

2018-01-09 02:36       2018-01-09 05:33       3 hours            986.09            996.93     



The actual cross-over points are accurate to the minute for the testing that I have done, however the figures are wildly inaccurate unless I am reading it wrong.

Please would it be possible for a developer to shed any light on this, and if possible give me a rough idea of how it works as I am developer myself, (with over 25 years experience) and will look into this and repair if you think it is in fact incorrect, and would be happy to share my update with you if you deem it fit.

Many thanks,
Stephen


  sqlite3 problem
Posted by: phoenix-blue - 01-08-2018, 08:06 PM - Forum: Technical Support - Replies (1)

Hi,

At this moment i'm switching from the Windows install to an Linux install.
The install itself is working, but when i for example want to download an test periode i get an error in the command line:

Code:
Error:

The plugin sqlite adapter expects the module sqlite3 to be installed. However it is not, install it by running:

    npm install sqlite3@3.1.4

Meta debug info:

Gekko version: v0.5.11
Nodejs version: v8.9.4

Strang part is that i have install sqlite3 but during the install i always (no matter what i do, even when i use the github install of sqlite3) see this error:
Code:
node-pre-gyp ERR! Tried to download(403): https://mapbox-node-binary.s3.amazonaws.com/sqlite3/v3.1.13/node-v57-linux-arm.tar.gz
node-pre-gyp ERR! Pre-built binaries not found for sqlite3@3.1.13 and node@8.9.4 (node-v57 ABI, glibc) (falling back to source compile with node-gyp)

Is there an other way to install sqlite3


  Gekko usage [newbie question]
Posted by: tog - 01-08-2018, 07:51 PM - Forum: General Discussion - Replies (1)

Hi there

This might be a newbie question!
How shall I use Gekko?
Is it a tool that monitor the BTC rate on various trading sites and make buy/sell decisions based on differences on those sites. Right?
As far as I understand correctly Gekko is about BTC only would that make sense to add more cryto-currencies and play on a given sites at buying/selling various currencies?

Thanks
G.

  Errors
Posted by: Drewskie - 01-07-2018, 10:18 AM - Forum: Technical Support - No Replies

First off I am very new to crypo and Linux.

I get the following errors using Kraken exchange:
Not sure if this is an error 
getPortfolio
aa { '0': null,
  '1': { error: [], result: { XXBT: '0.0050000000' } } }

But this is definitely an error

Any idea what I am doing wrong


  Does Gekko poll the exchange more than once per minute?
Posted by: redquicksilver - 01-07-2018, 07:44 AM - Forum: General Discussion - Replies (4)

Due to the highly volatile nature of the cryptocurrency markets and that the price can fluctuate from one second to the next, I would like to ask if Gekko polls each exchange more than once per minute, particularly when it comes time to act.  Once it is getting close to a 'buy' or 'sell' indicator being raised, does it poll the exchange at more regular intervals in order to get the best price?


  Which exchange?
Posted by: redquicksilver - 01-07-2018, 07:21 AM - Forum: General Discussion - Replies (4)

Hi anyone who is out there,

Just wondering which exchange to use, and if any one is better than the others.  Since there are 19 to choose from, I currently have an account with GDAX so just use that one.  Is there such a comprehensive list to cater for people who have accounts with all these exchanges, or is one account better for some reason unknown to me?

Many thanks,
Stephen


  Why isn't there a EMA strategy?
Posted by: redquicksilver - 01-07-2018, 07:06 AM - Forum: Strategy Development - Replies (8)

This is a question for askmike, but if anyone else can answer then please do:

I am fairly new to Gekko and am looking at the strategies available, the one that I am interested in is the EMA strategy after having read about it from Goomboo's posts from your recommendation.  It is also available on many of the online crypto websites, (GDAX cryptowat.ch) where you can select it from the menu and the EMA will appear along with the candles on the main chart.

Whilst I have been into cryptocurrencies for about a year, I was going to write a bot myself being a software developer but someone sent me a link to yours which I am using and perhaps modifying and creating it myself, however before I do, I thought there must be a reason why you create it yourself?
