 - Trade frequency is adjusted with a combination of `--period` and `--trend_ema`. For example, if you want more frequent trading, try `--period=5m` or `--trend_ema=15` or both. If you get too many ping-pong trades or losses from fees, try increasing `period` or `trend_ema` or increasing `neutral_rate`.
 - Sometimes it's tempting to tell the bot trade very often. Try to resist this urge, and go for quality over quantity, since each trade comes with a decent amount of slippage and whipsaw risk.

 - In a market with predictable price surges and corrections, `--profit_stop_enable_pct=10` will try to sell when the last buy hits 10% profit and then drops to 9% (the drop % is set with `--profit_stop_pct`). However in strong, long uptrends this option may end up causing a sell too early.
 - For Kraken and GDAX you may wish to use `--order_type="taker"`, this uses market orders instead of limit orders. You usually pay a higher fee, but you can be sure that your order is filled instantly. This means that the sim will more closely match your live trading. Please note that GDAX does not charge maker fees (limit orders), so you will need to choose between not paying fees and running the risk orders do not get filled on time, or paying somewhat high % of fees and making sure your orders are always filled on time.
