The red arrows are there on your Step Stochastic (ANina)
There are dots (like a warning a position may be coming) -- then the arrow --

The CAT50 seems to fail to produce arrows for some people's system -- but the arrows on the ANina (Step StochStatistic) are sufficient

ok that works

Excellent .. may it work WELL for you

We're near buy signal on gbp/usd.

That crossing is almost on the pivot line, be careful.

watch the usd/yen it has been leading the others for a few days made signals failed to break above pivot level took +20 already fibo piv support1, murry math 1/8th and float 61.8% are at the same levels just below 120ema

So you advise to wait when the price will be above pivot?

You have to make the decision, follow cat rules but if you see price struggling to breach the pivot or move away wait until there is a clear break. But don't take the trade if price has move to or above 20pips above 50ema. Wait while the next signal. You need to use descretion. There is no cat trade at the moment on cable.

When I use catfx50 and bb_macd together my Mt4 grinds down and takes ages to switch between timeframes, is there anything I can do apart from taking them off?

I had to stop using BB MACD .. same problem ... it is the BB MACD
