Hello,

I use the following strategy to help me in manual trading.

It draw an arrow up when the macd cross up and an arrow down when the arrow cross down.

What I would like is also to "print" in big letters on chart "BUY" when macd cross up until it cross down again and vice versa.

If somebody can help me, i will really appriciate.

We tested by backtesting in visual mode over 2011.12.13 - 2011.12.14 and by changing timeFrame variable to ONE_MIN

Thanks very much. It does work fine.
