crash using neural strategy

Open gianpaj opened this issue 5 years ago • 2 comments

System information

  • Have I written custom code (as opposed to using zenbot vanilla):
  • OS Platform and Distribution (e.g., Linux Ubuntu 16.04): Mac
  • Zenbot version (commit ref, or version): b1918f67f74c320e33179a3506fe3c725c3a6aa2
commit b1918f67f74c320e33179a3506fe3c725c3a6aa2 (HEAD -> unstable, origin/unstable, origin/HEAD)
Author: Maddcow <[email protected]>
Date:   Sat Feb 20 03:27:50 2021 -0500

    Added GDAX Sandbox option (#2653)
  • Zenbot branch: unstable
  • NodeJS version: v12.20.0
  • Exact command to reproduce (include everything): node zenbot sim --strategy 'neural'
  • Did I make any changes to conf-sample.js?:
conf.js 

c.selector = process.env.ZENBOT_DEFAULT_SELECTOR || 'binance.BTC-USDT'

// enable trailing sell stop when reaching this % profit (0 to disable)
- c.profit_stop_enable_pct = process.env.ZENBOT_PROFIT_STOP_ENABLE_PCT || 0
+ c.profit_stop_enable_pct = process.env.ZENBOT_PROFIT_STOP_ENABLE_PCT || 10
// maintain a trailing stop this % below the high-water mark of profit
- c.profit_stop_pct = process.env.ZENBOT_PROFIT_STOP_PCT || 1
+ c.profit_stop_pct = process.env.ZENBOT_PROFIT_STOP_PCT || 4

I was able to pass this error by running zenbot with this env NODE_OPTIONS=--max-old-space-size=8192 do some test and bump the space size to fit your needs.

example: NODE_ENV=production NODE_OPTIONS=--max-old-space-size=8192 zenbot trade --paper
