The huge number of ambiguous bars is a problem in your case. The backtest of this strategy is not reliable enough. You have to add additional filters or to change the entry logic.

I wondered about that at first but the strategy is not highly optimised. It simply goes long at the previous low plus the vertical shift. If I change the vertical shift parameters whenever the value ends in an 8,9, or 0 then there is a profit of around $20 - 30,000 but if the last number ends in a 1,2,3,4,5,6 or 7 there is a hugh loss of around $50- 60,000. So at a vertical shift of 70 my profit is $20,978 but at 71 it flips to a loss of $56,098. If I then increase the shift in increments of 1 to 78 it then  flips back to a $25,838 profit. Then at 81 it flips back to a $69,918 loss.

Most probably your strategy is over-optimized. It shows profit with exactly defined values of indicator parameters but if a small deviation occurs, the strategy fells.
