My every formula is failing. Attempting to build an ATS; using formula like in a paper trade. Trading on a single index, on day trading basis. On close when I see transaction logs - I see spikes (noise) is killing any profit and forcing me in red. As usual, buying on uptrend and selling in down. Now questions: a) Any suggestion how to avoid noise/spikes? b) Any good yet lean book which gives formula for a day trading. I saw some pivotel (H+L+C)/3 formula, but need more. Honestly, I am left with no energy/time to read long textual contents, just trying to spot simple 3-4 formulas to give a try. Please suggest.
