Plotting objects (buy / sell) arrows on a lower timeframe using higher time frame data.

Hello, 

Need help plotting higher time frame buy / sell arrows on a lower timeframe using data from a higher timeframe. When two moving averages cross over on the 1hr timeframe, can I plot (display) buy / sell arrows on a lower time frame (M15) using data from the H1 time frame. 

Any help will be highly appreciated. 

Below is a sample ma cross.

Thanks
