I've heard this claim occasionally by posters when they want to criticize other people that sell EAs. They say if the system is so profitable then creators would keep it to themselves, selling it to the public would just make it fail eventually. But my thinking is that would it not be in fact the OPPOSITE? Since trading is based on momentum and psychology more than anything else, if MORE people were using the same system, watching the same timeframe and they all receive a buy signal. This would just lead to a magnified runaway train effect where everyone on the system would buy, causing the price to shoot up, everyone else looking at the sudden momentum will also go "hey let's jump on board" leading to even higher price hikes. Then sell signal comes in, the people on the system will jump ship first, cause the price to go down, everyone else will look at that and go WTF, get panicked and sell, further magnifying the effect. So if anything having more people on the system would in theory make it MORE effective. Thoughts?
