the strategy I have back tested has a 93- 96% success rate on the 1 minute chart at 50x leverage
Some things work well for a week and then just stop working.
but that 4% will liquidate you

Are you sure it's 4%? There's no extra buffer the exchange adds at that leverage (it'll be unique to each exchange afaik).
The plan was one quick scalp a day a move of 1/2% which would gain me 5-10% on my account
I think the theory is sound just need to work on the execution

It might work if you have good execution and other things (like plans to stop for the day if nothing interesting happens).
There are ways of detecting certain moves that'll probably work in these strategies more than they won't - the issue is going to be to stop when something stops working and going back to backtesting.
The execution should have a stop loss though, it pulling back in the direction beyond your tp three times doesn't mean anything if you've liquidated three times in the process of doing that or one liquidation will empty your account.
