<li>Note that using <code>data.head()</code> would also work, however most indicators have some "startup" data at the top of the dataframe.</li>
<li>Some possible problems
* Columns with NaN values at the end of the dataframe
* Columns used in <code>crossed*()</code> functions with completely different units</li>
<li>Comparison with full backtest
* having 200 buy signals as output for one pair from <code>analyze_ticker()</code> does not necessarily mean that 200 trades will be made during backtesting.
* Assuming you use only one condition such as, <code>df['rsi'] &lt; 30</code> as buy condition, this will generate multiple "buy" signals for each pair in sequence (until rsi returns &gt; 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. </li>
