bullish momentum in tata steel

i am bullish on a tata steel for the target 520. it has taken a strong support on gann fann (1*2) @ 435 n soared fast upto 476 level. it is likely to touch 487 first where it can find some resistance becoz of 200 sma line. if stock closes above this line n the rising wedge (shown in figure) then stock will hit 416-420.
shorting can be seen below 435 level only.
