Cannot read property 'error' of null

[FFMG]

I get the above error rather often...
And it kills gekko and does not restart.

...
at set (..\exchanges\kraken.js:123:23)
...

It is rather annoying as gekko is killed and `I am not always able to restart it for a few hours.

Any suggestions?

It looks like the crash happens every time gekko tries to go long

config.watch = {

  // see https://github.com/askmike/gekko#supported-exchanges
  exchange: 'Kraken',
  currency: 'USD',
  asset: 'XBT'
}
...
config.tradingAdvisor = {
  enabled: true,
  method: 'PPO',
  candleSize: 5,
  historySize: 25,
  adapter: 'sqlite',
  talib: {
    enabled: false,
    version: '1.0.2'
  }
}
...
// PPO settings:
config.PPO = {
  // EMA weight (α)
  // the higher the weight, the more smooth (and delayed) the line
  short: 12,
  long: 26,
  signal: 9,
  // the difference between the EMAs (to act as triggers)
  thresholds: {
    down: -0.025,
    up: 0.025,
    // How many candle intervals should a trend persist
    // before we consider it real?
    persistence: 2
  }
};

I have the latest version

could you post the first 100 lines when gekko start? So that we can see what plugins are loaded.

[askmike]

I have a good idea what the problem is, but the strange thing is that it looks like the file that errors is not the most up to date version on the stable branch. Are you running an updated version? I hope to fix it asap nonetheless!

[FFMG]

I have the latest code, (from stable), and this is my first install, so as far as I can tell I have the latest.
Should I clone from another branch rather?

[askmike]

@FFMG could you please pull the develop branch and see if the error persists?

[FFMG]

It has been running for ~12hrs without issues, but I have not placed a 'long' order yet, and this seems to be when it crashed.
Will keep it running a little. longer.
