I had this program in other platform and I would like create the same trading system in ninja trader ,can somobody help me to translate this codes?
Entry long when : cross((EMA(5)>EMA(18) AND EMA(8)>EMA(28)),0.5)
AND Mom(7)>0 AND Mom(100)>0

Exit long when : Cross((EMA(5)<EMA(18) AND EMA(8)<EMA(28)),0,5)
OR Mom(40)<0

Entry short when : Cross((EMA(5)<EMA(18) AND EMA(8)<EMA(28)),0.5)
AND Mom(7)<0 AND Mom(100)<0

Exit short when : Cross((EMA(5)>EMA(18) AND EMA(8)>EMA(28)),0.5)

Hello,

Give it a try and I will give you pointers if you have questions.

This code, taken from the SampleMACrossOver Strategy may help you:
if (CrossAbove(SMA(Fast), SMA(Slow), 1))
EnterLong();
elseif (CrossBelow(SMA(Fast), SMA(Slow), 1))
EnterShort();

Thank's to answer..but I opened the link you send me but I not yet understand how can I code more condition together like this:
cross((EMA(5)>EMA(18) AND EMA(8)>EMA(28)),0.5)
AND Mom(7)>0 AND Mom(100)>0

If I well understand this codes it means that the condition would be fulfilled on the first bar when the EMA1>EMA3 and EMA2>EMA4 (in the LongEntryCond1 variable above, for example),cross() function because otherwise condition would be fulfilled for every bar when EMA1>EMA3 and EMA2>EMA4.but I can I write in ninja code?
Can I do this by strategy wizard?may you explain how?

Hello,

Try something like this to include multiple conditions:

if(time_to_trade && EMA(5)[0] > EMA(18)[0] && EMA(8)[0]>EMA(28)[0])
{

EnterLong();
time_to_trade = false;

}

The time_to_trade variable is a bool flag that is assigned a true or false value. You will need to declare and intialize it. You will also need to set it to true upon exiting the trade (neither shown here). This allows for one trade execution at a time.
