EA help.

I think if someone helps me get off the ground, I can learn to build, tweak, whatever.
buy signal when at the MACD +cross.
buy only when the RSI is level or moving up the last 3 periods, and above 50
buy only when exp MA 13, is above 34, 34 is above 89, and the 89 is up or even the last three period closes

sell signal when at the MACD -cross.
sell only when the RSI is level or moving down the last 3 periods, and below 50
sell only when exp MA 13, is below 34, 34 is below 89, and the 89 is down or even the last 3 period closes

stop loss of 10, trailing stop 10, take profit 50

open long position stops another open long position, but not close current short position. Opposite true too. short trigger stops another short, but not a long. This I would like to play with. If I could find where a position is taken with another like position, but only 1.....

Can someone help me out?
