A simple code for buying/selling when price cross EMA

Hi all,

I am new to ctrader algo and is wondering if somebody with a kind heart can help me with my first trading bot. The parameters are:

BUY when price cross above 10 EMA, provided that prices are ABOVE 200 SMA. Exit the current position if price cross down 10 EMA regardless of 200 SMA. Please note that bot will ONLY enter a long position when the two said criteria are met.

Its as simple as that. 

Thank you all
