I'll just add to Kris' comments, I agree with him about closing 50% with the objective of letting it run (or if you add on close the add on). So let's look at why we do that:
As M1 traders we take breakouts in the direction of the higher time frame (M5) trend. So with our attention on M5 we watch the alligator and the eWave and we wait until we have an indication of a clear direction, a clear trend. Then knowing that we want to get on board the M5 trend we dial down to M1 and look for the setup to get us in. But the real profit comes from hanging in there so long as the M5 chart continues to move, and avoiding the stop out that comes with the corrections of M1. So close 50% on M1 and then don't touch anything until M5 allows you to move your stop loss.
The real key to making this strategy successful is getting on board the M5 trend in its initial stages. So use three factors on M5 to indicate the start of the move:
1. Freshly opening alligator;
2. Fresh cross of eWave/close to ZL/start of new wave;
3. No divergence.
And if these three factors are present on the M5 chart, then get your free trade and then manage the remaining portion from the M5 chart. If you're not catching the very start of the M5 wave (remember all time frames are the same, so the start of an M5 move starts with an M5 S1 or S2) that's ok, but if you close 50% to get your free trade at least give it a chance to run by following AIMS levels on M1.
Just my opinion

Good luck!
Edit: I meant to mention this before but forgot. A good way to instill confidence in letting your remaining 50% run on the HTF is to take your entries when the HTF is not just open/trending, but when there are genuine entry opportunities from the HTF, as per the rules of S1 and S2. That’s probably not a very clear way to explain myself, but Bettina described this a long time ago as looking for S2 entries on the M5 chart, and nailing your M1 entries in these spots. In my opinion, this is THE best place to nail your M1 entries! Always best in pictures (I’ve used these pics before so sorry for the repetition, but that's the name of the game, and it's still great learning for me to hammer the concept home!)
