Manual pattern traders will always have an edge in every market. The Bunds currently has the highest percent of algos to human traders and yet I know hugely successful manual discretionary traders.
If algos controlled the world then algos could control the markets but this is not the case. Human Nature has and always will exist in the world. The need for money and the flows of currency will continue to exist based on human nature and that my friend is why people like me, manual traders, will always be able to beat the market.
This has been my experience as well although lately ive noticed a disturbing trend in crypto. During low volume periods there interestimg low volume pumps and dumps that look very mechanical to say the least.
