First of all, warm hello to all.
I am newbie and i admit it, but with at least 15+ years of exp in C++.
Working in IB - derivatives mainly, but unfortunately on the business side not trading at all. Got interested in Quant trading very much.

Intro:
I am learning very hard to understand the basics of quant trading currently building my first out of 2 applications. The Feeder - which generally speaking retrieves tick data (OHLC, price and volume) from Bitcoin Exchanges with a resolution of 1 minute (queries the markets every minute and stores the tick values in the database). No place to mention theory i read about in books and blogs.


Question:
Is it enough to get the tick values from exchanges to be able to backtest strategies ? Should i consider downloading orderbooks too?


Reason:
I am interested in backtesting and eventually quant trading Bitcoins, no options, futures or any derivatives. I understand BTC markets as FX.
