Our Smart Trading Tool comes with 5 activation licenses and it's a separate purchase for MT4 and MT5.
Something important to note is that the 5 activation licenses actually come from MQL5, not from us. So, if you ever need to reinstall Windows or move to a different computer, that counts as using one of your 5 licenses.
Now, if you happen to lose all 5 activations, you'll need to purchase the Smart Trading Tool again. Unfortunately, we can't sell it outside of MQL5 because that's the only way to get it up and running on the MT4/MT5 platform. Hope that clears things up for you!
