I agree, anytome I open the charts and notice the candlesticks are unusually short, I immediately know liquidity is low so several candles will have to form before I can make a reasonable profit. To solve this problem, I increase my lot size so that even with a few candlestick formations, I can still make a respectable profit while setting a small stop loss.
For example there was a day i noticed small candlesticks during London and i opened a 0.1 EUR/USD lot size trade and set a $5 stop loss at a fair enough distance from my entry. Now on a day where the candles were big, to set that same stop loss at that same distance, the stop would have been worth almost $12
