+## A note on Binance
+
+For Binance, please add `"BNB/<STAKE>"` to your blacklist to avoid issues.
+Accounts having BNB accounts use this to pay for fees - if your first trade happens to be on `BNB`, further trades will consume this position and make the initial BNB order unsellable as the expected amount is not there anymore.

+### Embedding Strategies
+
+FreqTrade provides you with with an easy way to embed the strategy into your configuration file. 
+This is done by utilizing BASE64 encoding and providing this string at the strategy configuration field,
+in your chosen config file.
+
+##### Encoding a string as BASE64
+
+This is a quick example, how to generate the BASE64 string in python
+
+```python
+from base64 import urlsafe_b64encode
+
+with open(file, 'r') as f:
+    content = f.read()
+content = urlsafe_b64encode(content.encode('utf-8'))
+```
+
+The variable 'content', will contain the strategy file in a BASE64 encoded form. Which can now be set in your configurations file as following
+
+```json
+"strategy": "NameOfStrategy:BASE64String"
+```
+
+Please ensure that 'NameOfStrategy' is identical to the strategy name!

+## 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. 
+
+## 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+It is my experience that GDAX sandbox candles may be 20+- minutes out of date.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+      # Check if dataframe is out of date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+                'Outdated history for pair %s. Last tick is %s minutes old',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
+```
+
+You could Hash out the entire check as follows:
+```
+       # # Check if dataframe is out of date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+        #         'Outdated history for pair %s. Last tick is %s minutes old',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
