how to add arrows to indicator

New comment
 

Hello, I need to develope and indicator who show arrow down with this condition:

if (iMA(Symbol(),0,10,0,MODE_SMA,PRICE_CLOSE,1)<iMA(Symbol(),0,40,0,MODE_SMA,PRICE_CLOSE,1) && iMA(Symbol(),0,10,0,MODE_SMA,PRICE_CLOSE,2)>iMA(Symbol(),0,40,0,MODE_SMA,PRICE_CLOSE,2))


and arrow up with this condition:

if (iMA(Symbol(),0,10,0,MODE_SMA,PRICE_CLOSE,1)>iMA(Symbol(),0,40,0,MODE_SMA,PRICE_CLOSE,1) && iMA(Symbol(),0,10,0,MODE_SMA,PRICE_CLOSE,2)<iMA(Symbol(),0,40,0,MODE_SMA,PRICE_CLOSE,2))


I tryed to search how to do on last days but with no result. I tryed adapting this one iI found but it doesn't works:


#property copyright "MAX"
#property link      "max"
#property version   "1.00"
