Chris, Ninja drains money for sure. Why dont you simply use MT4 for harmonic analysis instead, and trade those on Ninja if that is your preferred platform?
The cheap ones for MT4 are mostly as cheap as free... korharmonics 6.13, ZUP 135 or latest 136 and some others are also available.
For MT5 there is also a MTF harmonic monitoring tool, which is excellent (not updated any more).
I have seen very few things free for ninja, and thus I do not even know if there is a tool available for that. If you are desperate, I might help you to find one though if you really want ninja only and pay-pay-pay.
Suggestion, if you are happy with harmonics, try those combined with supply and demand zones, and increase your satisfaction (I guess MT4 indi is free for that too, or you can buy one for Ninja as well)...
Finally congratulations, to draw patterns on 1 min TF, with fib ret/ext tools, verify all internal ratios and confluences, I think is a big deal even if you are just on a couple of pairs, and you must be a master of patterns now, really impressive performance! I do envy you.
