# Sandbox API testing
|
||||
|
||||
Where an exchange provides a sandbox for risk-free integration, or end-to-end, testing CCXT provides access to these.
|
||||
Some exchanges provide sandboxes or testbeds for risk-free testing, while running the bot against a real exchange.
|
||||
With some configuration, freqtrade (in combination with ccxt) provides access to these.
|
||||
|
||||
This document is a *light overview of configuring Freqtrade and GDAX sandbox.
|
||||
This can be useful to developers and trader alike as Freqtrade is quite customisable.
|
||||
This document is a light overview of configuring Freqtrade to be used with sandboxes.
|
||||
This can be useful to developers and trader alike.

|

## Exchanges known to have a sandbox / testnet
|
||||
|
||||
* [binance](https://testnet.binance.vision/)
|
||||
* [coinbasepro](https://public.sandbox.pro.coinbase.com)
|

|
||||
* [phemex](https://testnet.phemex.com/)
|
||||
|
||||
!!! Note
|
||||
We did not test correct functioning of all of the above testnets. Please report your experiences with each sandbox.

## Configure a Sandbox account
|
||||
|
||||
When testing your API connectivity, make sure to use the following URLs.
|
||||
***Website**
|
||||
https://public.sandbox.gdax.com
|
||||
***REST API**
|
||||
https://api-public.sandbox.gdax.com
|
||||
|
||||

|
||||
In general, you should follow these steps to enable an exchange's sandbox:
|
||||
|
||||
# Configure a Sandbox account on Gdax
|
||||
- Figure out if an exchange has a sandbox (most likely by using google or the exchange's support documents)
|
||||
- Create a sandbox account (often the sandbox-account requires separate registration)
|
||||
- [Add some test assets to account](#add-test-funds)
|
||||
- Create API keys
|
||||
|
||||
Aim of this document section
|
||||
### Add test funds
|
||||
|
||||
- An sanbox account
|
||||
- create 2FA (needed to create an API)
|
||||
- Add test 50BTC to account
|
||||
- Create :
|
||||
- - API-KEY
|
||||
- - API-Secret
|
||||
- - API Password
|
||||
Usually, sandbox exchanges allow depositing funds directly via web-interface.
|
||||
You should make sure to have a realistic amount of funds available to your test-account, so results are representable of your real account funds.
|
||||
|
||||
## Acccount
|
||||
!!! Warning
|
||||
Test exchanges will NEVER require your real credit card or banking details!
|
||||
|
||||
This link will redirect to the sandbox main page to login / create account dialogues:
|
||||
https://public.sandbox.pro.coinbase.com/orders/
|
||||
## Configure freqtrade to use a exchange's sandbox
|
||||
|
||||
After registration and Email confimation you wil be redirected into your sanbox account. It is easy to verify you're in sandbox by checking the URL bar.
|
||||
> https://public.sandbox.pro.coinbase.com/
|
||||
|
||||
## Enable 2Fa (a prerequisite to creating sandbox API Keys)
|
||||
|
||||
From within sand box site select your profile, top right.
|
||||
>Or as a direct link: https://public.sandbox.pro.coinbase.com/profile
|
||||
|
||||
From the menu panel to the left of the screen select
|
||||
|
||||
> Security: "*View or Update*"
|
||||
|
||||
In the new site select "enable authenticator" as typical google Authenticator.
|
||||
|
||||
- open Google Authenticator on your phone
|
||||
- scan barcode
|
||||
- enter your generated 2fa
|
||||
|
||||
## Enable API Access
|
||||
|
||||
From within sandbox select profile>api>create api-keys
|
||||
>or as a direct link: https://public.sandbox.pro.coinbase.com/profile/api
|
||||
|
||||
Click on "create one" and ensure **view** and **trade** are "checked" and sumbit your 2FA
|
||||
|
||||
- **Copy and paste the Passphase** into a notepade this will be needed later
|
||||
- **Copy and paste the API Secret** popup into a notepad this will needed later
|
||||
- **Copy and paste the API Key** into a notepad this will needed later
|
||||
|
||||
## Add 50 BTC test funds
|
||||
|
||||
To add funds, use the web interface deposit and withdraw buttons.
|
||||
|
||||
To begin select 'Wallets' from the top menu.
|
||||
> Or as a direct link: https://public.sandbox.pro.coinbase.com/wallets

||||
- - Deposit Funds Bitcoin
|
||||
- - - Coinbase BTC Wallet
|
||||
- - - - Max (50 BTC)
|
||||

|
||||
|
||||
*This process may be repeated for other currencies, ETH as example*

# Configure Freqtrade to use Gax Sandbox
|
||||
|
||||
The aim of this document section
|
||||
|
||||
- Enable sandbox URLs in Freqtrade

- Configure API

- - key
|

- - passphrase
|

## Sandbox URLs
|
||||
### Sandbox URLs
|
||||
|
||||
Freqtrade makes use of CCXT which in turn provides a list of URLs to Freqtrade.
|
||||
These include `['test']` and `['api']`.
|
||||
|
||||
- `[Test]` if available will point to an Exchanges sandbox.
|
||||
- `[Api]` normally used, and resolves to live API target on the exchange

|
||||
|
||||
!!! Tip "Different data directory"
|
||||
We also recommend to set `datadir` to something identifying downloaded data as sandbox data, to avoid having sandbox data mixed with data from the real exchange.
|
||||
This can be done by adding the `"datadir"` key to the configuration.
|
||||
Now, whenever you use this configuration, your data directory will be set to this directory.
|
||||
|
||||

|
||||
|
||||
## You should now be ready to test your sandbox
|
||||
|
||||
Ensure Freqtrade logs show the sandbox URL, and trades made are shown in sandbox.
|
||||
** Typically the BTC/USD has the most activity in sandbox to test against.
|
||||
Ensure Freqtrade logs show the sandbox URL, and trades made are shown in sandbox. Also make sure to select a pair which shows at least some decent value (which very often is BTC/<somestablecoin>).

## GDAX - Old Candles problem
|
||||
## Common problems with sandbox exchanges
|
||||
|
||||
It is my experience that GDAX sandbox candles may be 20+- minutes out of date. This can cause trades to fail as one of Freqtrades safety checks.
|
||||
Sandbox exchange instances often have very low volume, which can cause some problems which usually are not seen on a real exchange instance.
|
||||
|
||||
To disable this check, add / change the `"outdated_offset"` parameter in the exchange section of your configuration to adjust for this delay.
|
||||
Example based on the above configuration:
|
||||
### Old Candles problem
|
||||
|
||||
```json
|
||||
"exchange": {
|
||||
"name": "gdax",
|
||||
"sandbox": true,
|
||||
"key": "5wowfxemogxeowo;heiohgmd",
|
||||
"secret": "/ZMH1P62rCVmwefewrgcewX8nh4gob+lywxfwfxwwfxwfNsH1ySgvWCUR/w==",
|
||||
"password": "1bkjfkhfhfu6sr",
|
||||
"outdated_offset": 30
|
||||
"pair_whitelist": [
|
||||
"BTC/USD"
|
||||
```
|
||||
Since Sandboxes often have low volume, candles can be quite old and show no volume.
|
||||
To disable the error "Outdated history for pair ...", best increase the parameter `"outdated_offset"` to a number that seems realistic for the sandbox you're using.
