Almost everyone bases their price on those or on bitstamp or coinbase, and then convert to local currency.
For local, just look at rebit.ph and coins.ph and btcexchange.ph which are, in my humble opinion, the top 3 in Metro Manila.
Hindi naman pwede magkalayo ng presyo dahil sa arbitrage. You can make money when the price differences are big, but it's risky even if you can do it all within the hour.
I tried. You would need a few hundred thousand pesos, deposit to one exchange, trade to bitcoin, withdraw, deposit the BTC to another exchange, sell to pesos, withdraw. That's one cycle that will take the better part of the day.
The next day, wala na yung opportunity kasi lahat ng kagaya ko ginawa na.
Ang kikitain mo? mga 1% to 2% to 3%, so sa 100,000 (hundred thousand) pesos, mga up to 3000 (three thousand) pesos.
Sana magawa mo araw araw, eh, di okey, pero kailangan mo ng pera. At, pwede mag back fire, papano kung biglang bumagsak yung presyo, eh, di, patay ka na.
Don't try with money you can't afford to lose.
I also usually check these sites to check for bitcoin values. However, if you would search randomly through google, it would show you the current bitcoin value. The key here is to always check several different sites to compare which one is the closest with the real value or at least get their average to tell you where bitcoin values play around. It's never bad to be sure and check many sources because the more sites you have on your list, the reliable information you would get because I am sure that most of them would want to be accurate to have more users. Another aspect you can consider is that it should user-friendly both via computer or mobile, so you can conveniently use it anywhere.
