How to trade several stocks in same algo ?

Hi,

This algo trade 1 stock when crossover appears on SMA20, SMA5 and MACD is > 0 (positive). Any idea how I can add e.g. 10 or more stocks to same algo and trade with same indicators and trade e.g. 10% of portfolio on each stock ?

In this example only 10% of portfolio is allocated to 1 stock. 

Best regards

Karsten
