It wont work
Open up a 1 minute chart of anything your interested in trading and take a bunch of demo trades over the next few weeks, perhaps opening trades every hour or so, and letting them run for a couple of hours. Dont set stops, and dont set targets Once you have a few hundred trades, calculate the profit / loss for each trade on the close of each bar.
Roughly speaking you'll find a 50% win rate, and 80% of the trades just sort of meander between positive and negative territory either resulting in a small win, or small loss. 10% of the trades will result in large gains where you where lucky enought to catch a trend, and 10% will be large losing trades, where the trend went against you.
Thats the benchmark that a complete moron with absolutely no trading experience should be able to achieve, pretty much break even minus transaction costs +/- a degree of "noise" (and I'll quite happily bet my shirt most reading this wont be able to beat that

)
The next step is repeating the experiment, but specifying targets and stops to give you a variety of reward to risk scenarios. What you'll find is that the 1:1 reward:risk ratios will result in pretty much the same outcome, a 50/50 win loss and break even minus transaction costs.
If you half the risk, (or double the reward), your win rate will simply decrease, although you should achieve pretty much the same break even scenario.
if you double the risk, or half the reward, your win rate will increase, but you'll end up with the same break even - transaction cost scenario.
Before anyone starts claiming the 1 minute timeframe is noise, you'll get the same outcome on any timeframe you care to try this on.
This is as good a starting point for developing a trading strategy as you are likely to get, and it allows you to start asking questions such as can you limit losses ? can you let winners run ?, can you perhaps time the entry ?, does timing the entry actually result in smaller stops for winning trades ?, whats a suitable size for a stop ?, are trades taken with the trend more successful than those taken against the trend ? (and what is a trend, and how do you measure it), do indicators help ?, do candle patterns help ?, whats happening in other timeframes ?, are the number of consecutive gains or losses effected by your strategy ?, what elements of TA are useful ? support / resistance ?, do fibs work ? are oscillators useful ?, does divergence work ?, can you optimise a staking plan or money management strategy ?
The only way you'll ever know if you have an edge is to measure the distribution of gains and losses from your edge against the distribution from a random sample.
Ironically by the time you've spent a couple of years staring at charts to answer these sorts of questions, you'll have gained enough exposure and screen time to develop an instinctive feel for price action, and formulated the other 1001 questions that need to be considered.
