Topic: Gekko - a javascript trading bot and backtesting platform - page 28. (Read 147846 times)

There is no set price to buy and sell at - it's does it based on the EMA rate

Wait where do I set the trade I'm trying for a different coin not btc I think I just set it to the coin I want but than where do I put the price I want to buy and sell at

let me know if it works!

Did you see this document? Anyway here is how you can configure Gekko to auto trade on BTC-e:


The API key and secret can be generated on the profile page on btce. Gekko only need trade rights.

I'm off to bed now.

I have finally found the bug regarding BTC-e monitoring. Gekko broke over BTC-e monitoring because bitcoinCharts (the API Gekko uses to get trade data from BTC-e) changed the way services can ask for trade data (silently).

Current workaround for BTC-e users:

• Set debug in the config to true (line 145)
• Set the candles to something lower than 40 (line 22)
• Run Gekko
• Check whether the calulcated EMAs are NaN, if they are lower the 40 number

The reason the 40 number can be different is that now bitcoinCharts will return the last 2000 trades, and how long ago the oldest one happened depends on the market.

That's strange... I get no update after an hour (interval is 60 in config.js)... in fact I left it for a day and no update. It just checks the EMA once and then no more... but continues running.
If I quit and rerun it does the same - gives one advice and then no more

By default it runs every hour.

Can i use this to trade LTC at BTC-e?

Nope, no web page.

Anyway, using Bitstamp all of a sudden, everything is NaN

ok no page or anything so it's all done in terminal but why does mine site there and thats all?

How do you know it's still working? I ran it, it gave one trade advice... and nothing else since...

config.EMA = {
  // timeframe per candle
  interval: 60, // in minutes
  // EMA weight (α)
  // the higher the weight, the more smooth (and delayed) the line
  short: 10,
  long: 21,
  // amount of candles to remember and base initial EMAs on
  candles: 200,
  // the difference between the EMAs (to act as triggers)
  sellTreshold: -0.25,
  buyTreshold: 0.25
};

When real trading is enabled, is there some kind of limit I can impose on it so it uses a small amount of my money for trading instead of my whole balance?
Again, for Bitstamp.
