using just 1 chart can be successful..but..it all depends on how much you have..how much you can afford to lose per trade..and how good you are at fighting greed
if you have deep pockets..like the market makers..then you can afford to let price run against you for a certain amount of time.. however..they also get caught out when the SHTF..
if you look at the ES volume..then compare it to the OI..what do you think you will find!
you can make loads of money trading..but..you can also lose loads of money..and..losses are always much quicker than gains.. for obvious reasons
so..it comes down to..amount of risk capital available..understanding the best market to trade in relation to how much you can afford to lose..then..the easy bit..operating a tested and proven methodology that will yield positive results with a set number of trades..over a given time frame
forget about making consistent money with a few trades..it will never work..as..for anything to work..you must AVERAGE it out..no other way..no matter what banana eating monkey tells you otherwise
"you can NOT make a silk purse out of a sow's ear"
no matter how hard you try !!!!!
