Mutual fund or ETF?

So I saw a trader give tips and it sounds so good to be true.

1. The trader said instead of MF use ETF as it doesn't have exit load and the exp ratio is less in ETF

2. Buy ETF sips when the market is at dip

3. Use the ETF capital and pedge it and do intraday trading by using algoroom ( algorithm which has templates and will trade for you) and set a algo for 1% as a stop loss and 1 % profit.( If the trade is Profit or loss for 1 perc the trade will stop) This will give approx 12+% with the return you where getting for ETF sips.

Does this strategy works??
