RE: [SHARE] GAB - Gekko Automated Backtests - simpsus - 04-10-2018
I have the same situation with multiple strategies:
backtesting in gekko works fine.
parameter iteration with gab immediately gives me curl status 500 with
Error: non-error thrown: Child process has died.
at Object.onerror (/var/www/html/gekko/node_modules/koa/lib/context.js:105:40)
at process._tickCallback (internal/process/next_tick.js:109:7)
in the gekko console.
As this is the case with different strategies and single runs with gekko work fine: Do you have an idea what is happening or what I could to to investigate? Thanks!

A curl status of 500 mean SERVER ERROR. This means that the parameters you tried to send does not work.
It could be for any number of reasons, try with a simple strategy. If nothing works you most probably have a problem with your setup.
Also try running <your_server>/gab/sanitycheck.php

the user.config file is point to gekko ui localhost and gekko is running as i'm getting the gab/system/post.php message in terminal.
Am i missing something?
I've never seen a 'Not found' in the CLI-version, maybe you're trying to do something where something cannot be found?
Make sure the stuff you're trying to run is valid and that GAB actually has an endpoint to run against. Here's a typhical CLI-config file saved as rbba_50_xmr.sh and ran via $ . run.sh cli/rbba_50_xmr.sh
Code:
# Server (with php) + dir
SERVER="http://localhost:8889"
DIR="/gab/"
# TOML for strategy, just copy-paste the params and add dynamic variables
STRATEGY="RSI_BULL_BEAR_ADX"
TOML="
[SMA]
long = 100:1000,100
short = 10:90,10
[BULL]
rsi = 15:25,5

low = 40:50,5
mod_high = 10:20,5

# settings, rest of the settings -- make sure you actually have the dataset

# dates, use Y-m-d format e.g. 2018-12-24

Thank you very much. It was the parameter ranges. I was too big in the range.

You have some value in some strategy that messes things up. It basically tries to evaluate integer or float values, if you got "thing = mystuff" it will not understand what you mean since 'mystuff' is not a valid integer or float (a number) and thus returns "unknown primative".
This is a current bug where GAB can fail, it basically has to do with issue #15:
https://github.com/tommiehansen/gab/issues/15
So to solve this try to temporarily remove (or move) any strategy that uses exotic parameters which are not floats or integers (numbers).
RE: [SHARE] GAB - Gekko Automated Backtests - monty - 04-14-2018
I am doing something wrong.... pls help
Strategy is : RSI_BULL_BEAR_ADX
Parameters:
[SMA]
long = 1000
short = 50
[BULL]
rsi = 10
high = 80
low = 60
mod_high = 5
mod_low = -5
[BEAR]
rsi = 15
high = 50
low = 20
mod_high = 15
mod_low = -5
[ADX]
adx = 3
high = 70
low = 50
Same error on RSI_BULL_BEAR, DEMA, MACD...
