I am using the Semaphore for years now and it is a wonderful tool if you learn how to get the most out of it.

My suggestion is to watch higher TFs and when you get a bunch of 3's on charts, you will be almost 100% sure you hit the price in the lottery. Like M15, M30, H1 and even H4, you hit the casino.
trust me, those situations occur on a regular basis and pay lots of pips.

Also I have been using a setup where I would enter a trade opposite of what the dot indicates, like a 3 dot up on the M5, if the price keeps going against me, I enter another position some 15-20 pips after that and then wait for the retrace to pay me. I works, but not the best system for me so far.

Don't want to sound negative, but I don't see this really cutting it in a live account.
The semaphore was designed as  trend reversal indicator, combines with a ZZ to mark it easier.

Now if the issue would be build on the 2 dot, it makes more sense to me, as that is a warning for a 3 dot to show up higher lots of time.
