An Expert Advisor over multiple time frames using MACD & EMA indicators

IF: The bar (on a bar chart) on a 5 minute chart closes greater than (>) the 50 period EMA,
&IF: (On a 5 minute chart) The MACD 12 period Fast EMA and 26 period Slow EMA main moves
greater than (>) the MACD 9 period SMA Signal line,
&IF: The bar (on a bar chart) on a 1 hour chart closes greater than (>) the 50 period EMA,
&IF: (On a 1 hour chart) The MACD 12 period Fast EMA and 26 period Slow EMA main moves
greater than (>) the MACD 9 period SMA Signal line,
&IF: The bar (on a bar chart) on a 4 hour chart closes greater than (>) the 50 period EMA,
&IF: (On a 4 hour chart) The MACD 12 period Fast EMA and 26 period Slow EMA main moves
greater than (>) the MACD 9 period SMA Signal line,
THEN: Buy / open long order.
· So three timeframes (5 minute, 1 hour, and 4 hour), in one system.
· When: The bar closes greater than the 50 period EMA on all three time frames,
And: The MACD 12 period fast EMA and 26 period slow EMA-main moves greater than the
MACD 9 period SMA-signal line, on all three time frames,
Then: a long order is triggered.
· I am currently only interested in trading using mini lots, so I plan on continuing to make 0.10 lot
size trades for now, but is there a way to have the option incorporated in the robot to have a set
(but adjustable) amount of account equity to use for each trade? The same with stop losses and
trailing stops (For example: only use 2% of equity and 20 pip trailing stop).
