-# Location of the data
-data_location = Path(user_data_dir, 'data', 'binance')
-# Pair to analyze - Only use one pair here

-### Load and run strategy

-                            'user_data_dir': user_data_dir,

-
-# Generate buy/sell signals using strategy
-df = strategy.analyze_ticker(candles, {'pair': pair})
-```
-
-### Display the trade details
-
-* Note that using `data.tail()` is preferable to `data.head()` as most indicators have some "startup" data at the top of the dataframe.
-* Some possible problems
-    * Columns with NaN values at the end of the dataframe
-    * Columns used in `crossed*()` functions with completely different units
-* Comparison with full backtest
-    * having 200 buy signals as output for one pair from `analyze_ticker()` does not necessarily mean that 200 trades will be made during backtesting.
-    * Assuming you use only one condition such as, `df['rsi'] < 30` as buy condition, this will generate multiple "buy" signals for each pair in sequence (until rsi returns > 29). The bot will only buy on the first of these signals (and also only if a trade-slot ("max_open_trades") is still available), or on one of the middle signals, as soon as a "slot" becomes available.  
-
-```python
-# Report results
-print(f"Generated {df['buy'].sum()} buy signals")
-data = df.set_index('date', drop=True)
-data.tail()
-```

 The output will show the last entry from the Exchange as well as the current UTC date.
 If the day shows the same day, then the last candle can be assumed as incomplete and should be dropped (leave the setting `"ohlcv_partial_candle"` from the exchange-class untouched / True). Otherwise, set `"ohlcv_partial_candle"` to `False` to not drop Candles (shown in the example above).
