Quote from trickshot:
A 4 tick profit on 100 contracts isnt the same thing as a 400 tick profit on one contract, far from it. The smaller your profit targets the worse you are affected by spreads (which is 1 tick, or a whopping 25% of your profit target if you are targeting only 4 ticks), slippage (could be a disaster if you are holding a huge position and the market suddenly spikes) and commissions, no retail trader can overcome such incredibly high odds in the long run, its suicide.
Besides, the HFTs already dominate these time frames, they have a clear advantage over retail on the lower time frames so good luck competing with them.
The reason why trading was so profitable a few years ago was due to the high volatility and very high "tradeable" range, it made the lower time frames work like the higher time frames. What usually takes days or even weeks to develop can happen in one day, I could easily risk 2 pts to make 20 pts even if it was just an intraday trade, comms, slippage and spreads become irrelevant in these situations.
There is still reasonable range and volatility in commodities and fx, but imo those instruments dont trend very well on the lower time frames. Massive price spikes that reverses almost immediately are very common on instruments like GC or CL, its too whipsawy for my liking, though I think it is definitely possible to develop strategies to trade them profitably because there is gd range and volatility.
