The most important core ruleset the market follows... Above candle counts and cycles... Is the range break rules. There are a few different ways to solve the odds. Higher timeframe cycles, moving averages. Oversold/overbought levels... Etc... Ill give you a tip... When certain ranges are broken... The market has a specific set of target prices that the market will need to test. The reaction to the market to those target prices (in time) tells you the odds of trend stopping at the target price or continuing on to the next target price. There are other better solutions to calculating things, but this is all ill give you.
