Cannot read property 'toString' of null

[YuriyTigiev]

System information

• Have I written custom code (as opposed to using zenbot vanilla):
• OS Platform and Distribution (e.g., Linux Ubuntu 16.04): Microsoft Windows [Version 10.0.17134.228] 64 bit
• Zenbot version (commit ref, or version): 4.1.0
• Zenbot branch:
• NodeJS version: 8.11.4
• Python version (when using a python script): 2.7.14 64 bit
• Exact command to reproduce (include everything): zenbot sim --strategy cci_srsi binance.BNB-BTC
• Did I make any changes to conf-sample.js?: No. I have copied conf-sample.js as conf.js and add a binance key.

Describe the problem

When I run zenbot sim --strategy cci_srsi binance.BNB-BTC it returns error.
This command worked perfectly a few hours before. I have recreated zenbot4 database.
I have used update.bat and npm install binance. Nothing was changed.

Source code / Error logs

Include any logs or source code that would be helpful to diagnose the problem. If including tracebacks, please include the full traceback. Large logs and files should be attached. Try to provide a reproducible test case that is the bare minimum necessary to generate the problem.

c:\zenbot>node zenbot.js sim --strategy cci_srsi binance.BNB-BTC

I have done an additional test

Doesn't work
c:\zenbot>node zenbot.js sim --strategy cci_srsi binance.BNB-BTC --period=1m

Works
c:\zenbot>node zenbot.js sim --strategy cci_srsi binance.BNB-BTC --period=1h

[YuriyTigiev]

For (1h) period the bot use data only for 17 days. But I have downloaded data for the last 90 days.
zenbot backfill --days 90 binance.BNB-BTC

node zenbot.js sim --strategy cci_srsi binance.BNB-BTC --period=1h

end balance: 1000.00000000 (0.00%)
buy hold: 1016.89298941 (1.69%)
vs. buy hold: -1.66%
0 trades over 17 days (avg 0.00 trades/day)
