sub-penny increment does not fulfill minimum pricing criteria

[SeverinJB]

It appears Alpaca only accepts two decimals for prices if the price is above $1.00 (see doc).

The fix should be to round the order price up if the total order is above $1.00. For instance, instead of $1.005, the order would be $1.01.

For simplicity, the alpaca_trade_executor now uses round() to round the decimal to two places if the price is bigger than 1.

However, from a logical standpoint, it needs to be investigated if the price should rather be rounded up for 'side=buy' and rounded down for 'side=sell'.

Keep this open as the above needs to be looked into.
