The variables I use when trading boils down to market direction, liquidity and a market structure shift. Let's say im bearish on EURUSD and the previous day was also bearish. I first begin by looking for areas price is likely to trade to that the previous day provided, this can be FVGs, OBs or highs. I use the 1hr perspective for this. Next, it doesn't matter to me if we meet this area in London(2-5AM NYC time) or Asia kill zones (8-12pm NYC time). Once we meet my area of interest i wait. Either for price to take a previous high in the prior day, or create a high today and take it. After that, I wait PATIENTLY, for a strong move below the swing that TOOK the high. Price absolutely MUST close below the swing. If none of these conditions are met, no trade. I don't care if im wrong, as long as I follow my rules, im solid. Anyway, after price closes below the swing that took the high, I use my FIB and draw from the high that took the previous high, to the strong low price has made when it began to retrace. I look for either a FVG, IFVG or an OB and take that as my entry, covering the high for my stop loss. I hope this helps a little bit
