Use the output of the free indicator "MA Trend SG".

The EA would place buy / sell signals on the following conditions:

BUY - when new arrow is BUY signal, and previous arrow was SELL signal
SELL - when new arrow is SELL signal, and previous arrow was BUY signal.

In addition the EA would have the following features.

1. Magic Number
2. Maximum number of open orders.
3. Stop Loss
4. Take Profit
5. Trailing Stop [Start point, offset, Step Size]
6. Lot Size
7. Trading Time [Start/End]
8. Enable Alert for buy/sell signal ( if EA only used as indicator )
9. Enable Auto-Trading ( if EA used as full EA )
10. Draw arrows when trades placed.
