Do you have a specific candle pattern you’re using as a reference? I guess you can call it lagging… the best price to enter long is going to be at what looks like a bearish candle. Indicators are just a different look at historical pricing as their formula derives from historical prices.
It’s going to be based on your risk appetite.
Ex1:
If you can find a reliable candle pattern, meaning it wins ~50% of the time, you can plan on entering with 1 lot, loses, enter next setup with 2 lots, wins. Track the max losses and curtail your position size to fit the risk of ruin. Maybe after a 2nd entry, lower the profit target, maybe 3rd entry will have a breakeven target.
Ex2:
In the case of entering on a break of a bullish pinbar, you can position small enough to plan to reenter the same size on break of the tail if profit target isn’t hit… giving you an average entry of middle of the candle.
The possibilities are endless. Backtest, curtail position size based on results, try it on static take profit levels, try it on dynamic tp based on average price, ect.
