what wrong of my code???

my ea  can run the sl and tp as well as i wanna , but only one thing is that when the OrderClosePrice is bigger or lesser than 400 pips but my T/P do not move to -200pips(because i want it be my stop lose) 

my original idea is that for example i order a buy eur/usd at 1.12093 , tp was 1.12193 (100pips).  then the tp will move at 1.11893(-200pips)  afther the market price is 1.11693(-400pips)



pls help me to fix it out
