New Backtest IDE Video & Speed Boost

I had correspondence about the previous IDE video blacking out. It could be a browser bug.

In any case, after trying to record an updated video covering API features, I realised the IDE was bringing my 2008 laptop to its knees.

The long weekend was spent getting more intimate with Lazy.js; swearing; and making the code thousands of times quicker.

Now its silky smooth plus you can backtest strategies with daily holding periods!
