<div class="bbWrapper">I tried the tool for a while and it seems versatile and intuitive. One good thing is that it is web-based, nothing to install on a PC. I noticed as well that it doesn't support weekly options. Also in backtesting it only provides end-of-day options data, no intraday increments. I checked with their support team and they confirmed it. So far I have used on ONE for backtesting, it allows 5-minute increments.</div>
