It's important to understand what naked trading is based on - your visual memory and the brain's ability to compare two images with attention to details.
If you are a visual type, if you actually remember (some) price charts, you can try it. It may require a slightly different approach - for example no fixed stop or TP levels (eg. always 50 pips), but rather, according to the market. For a long, stop could be below a recent low, and a profit target could be below a previous high. (Of course if the stop would be too far for your risk appetite, you can decide not to take a trade, or open a smaller position. Naked trading is absolutely not mechanical, you have to be flexible)
In fact there is only one way to learn it - practice, practice and practice. Trade small positions. Sooner or later you will develop a sense /a second nature, as Wyckoff says in his 1919 book, The daytrader's bible/ and you will have a pretty good idea of what might and what might not work in a given situation.
Anyone still trading naked here?
