- Enable sandbox URLs in Freqtrade
- Configure API

- Enable sandbox URLs in Freqtrade

## Sandbox URLs
Freqtrade makes use of CCXT which in turn provides a list of URLs to Freqtrade.
These include `['test']` and `['api']`.
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
To make use of sandbox / test add "sandbox": true, to your config.json
```
```json
"exchange": {
"name": "gdax",
"sandbox": true,
"key": "5wowfxemogxeowo;heiohgmd",
"secret": "/ZMH1P62rCVmwefewrgcewX8nh4gob+lywxfwfxwwfxwfNsH1ySgvWCUR/w==",
"password": "1bkjfkhfhfu6sr",
"outdated_offset": 5
"pair_whitelist": [
"BTC/USD"
```
Also insert your
- api-key (noted earlier)
- api-secret (noted earlier)
- password (the passphrase - noted earlier)

## GDAX - Old Candles problem
It is my experience that GDAX sandbox candles may be 20+- minutes out of date.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
To disable this check, edit:
>strategy/interface.py
Look for the following section:
```
# Check if dataframe is out of date
signal_date = arrow.get(latest['date'])
interval_minutes = constants.TICKER_INTERVAL_MINUTES[interval]
if signal_date < (arrow.utcnow().shift(minutes=-(interval_minutes * 2 + 5))):
logger.warning(
'Outdated history for pair %s. Last tick is %s minutes old',
pair,
(arrow.utcnow() - signal_date).seconds // 60
)
return False, False
```
It is my experience that GDAX sandbox candles may be 20+- minutes out of date.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.
You could Hash out the entire check as follows:
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:
```json
"exchange": {
"name": "gdax",
"sandbox": true,
"key": "5wowfxemogxeowo;heiohgmd",
"secret": "/ZMH1P62rCVmwefewrgcewX8nh4gob+lywxfwfxwwfxwfNsH1ySgvWCUR/w==",
"password": "1bkjfkhfhfu6sr",
"outdated_offset": 30
"pair_whitelist": [
"BTC/USD"
```
# # Check if dataframe is out of date
# signal_date = arrow.get(latest['date'])
# interval_minutes = constants.TICKER_INTERVAL_MINUTES[interval]
# if signal_date < (arrow.utcnow().shift(minutes=-(interval_minutes * 2 + 5))):
# logger.warning(
# 'Outdated history for pair %s. Last tick is %s minutes old',
# pair,
# (arrow.utcnow() - signal_date).seconds // 60
# )
# return False, False
```
Or inrease the timeout to offer a level of protection/alignment of this test to freqtrade in live.
As example, to allow an additional 30 minutes. "(interval_minutes * 2 + 5 + 30)"
```
# Check if dataframe is out of date
signal_date = arrow.get(latest['date'])
interval_minutes = constants.TICKER_INTERVAL_MINUTES[interval]
if signal_date < (arrow.utcnow().shift(minutes=-(interval_minutes * 2 + 5 + 30))):
logger.warning(
'Outdated history for pair %s. Last tick is %s minutes old',
pair,
(arrow.utcnow() - signal_date).seconds // 60
)
return False, False
```
