Seeing this issue in 1.8.0, 1.8.1 and 1.8.1.1 with Go 1.17.5. Maybe this is reason why my Binance funds are not reflected in the dashboard?

websocket: bad handshake

Using Docker approach this messages appears on providing credentials via the Admin page, which worked before in v1.9.0 and before without issues

Getting an build issue on Go 1.6 or 1.7.5 for 1.8.1, 1.8.0 is fine.

$ go build .
# github.com/aleibovici/cryptopump/mysql

Hey Andre,

It's much easier speaking here compared to twitter so I hope you don't mind me opening an issue. I got mysql running on my unraid server as docker. I'm able to connect to it and I've imported your .sql file into it like this:

$ docker exec -i xxxxxxxx mysql -uroot -pthepassword cryptopump < /path/to/cryptopump.sql

now I'm able to start cryptopump under Visual Studio Code. I have set the Binance API and secret and enabled spot trading.

Here's my config.yaml:

config:
  apikey: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
  apikeytestnet: 
  buy_24hs_highprice_entry: "0.0005"
  buy_24hs_highprice_entry_macd: "20"

  exit: "false"

  testnet: "false"
  tgbotapikey: 
  time_enforce: "false"
  time_start: 04:00AM
  time_stop: 07:00PM

So, when starting up I get:

`Exception has occurred: panic
"runtime error: invalid memory address or nil pointer dereference"

Do you have any idea what might be wrong in this case?

Hi Andre,

Here is a fix for an unhandled error that caused the bot to disconnect from binance server.

time="2021-08-05 02:44:01" level=debug msg="cryptopump/algorithms.WsKline.func2 - websocket: close 1001 (going away)" orderID=0 threadID=c435ggsrs38slni7mhhg
time="2021-08-05 04:40:02" level=debug msg="cryptopump/algorithms.WsUserDataServe.func2 - websocket: close 1001 (going away)" orderID=0 threadID=c435ggsrs38slni7mhhg

It is not easy to reproduce the error to verify the fix, not until it happened again at least..

Changes to accomodate dynamic loading of real-time websockets data into html via javascript and a API in /sessiondata. Known bug: plotter widget size when embedded into json object.
