Very true. INT is not for everyone, depends on your attitude to risk. But hopefully the fact that it retains the "Set and Forget" nature of NT will be beneficial for some people. Definitely needs proving out over a longer period. I continue to paper trade vanilla NT. As soon as I get a month where NT is in overall profit for the month but INT records an overall loss for the month, I will seriously reconsider.
Until then, I trade as follows:
* INT on NT trade days, UNLESS the MA Spread is 1.
* When it is an NT trade day but MA Spread is only 1, I trade MINT instead.
* On "no-trade" NT days I apply MINT to the EUR/USD market instead.
This approach worked really well in June. Of course, that's not to say it will continue to do so, but as you so rightly say, only time will tell.
