HI isatrader!I found that the 60-week moving average in the stock market is more accurate. Do you agree?

I wouldnt say more accurate. I've personally found the 50week often fits better stocks movement, however its only supposed to be used as a guide. 
"where is price in relation to the average" makes the average itself very very flexible in terms of length
also, considering recent market movements, the 50 or even worse your 60sma makes your stop loss further away and you really dont want that right now

Especially with 7-10% swings in any direction being normal at the moment.
