Random/coin toss entries are fine as long as you understand that if you just randomly enter at a random time in a random direction then all you will be doing is giving money to your broker in the form of spread and other fees. Random entry is fine as long as you don’t have random direction. The direction has to give you an edge that is of a higher percentage chance that you are going to be right than the spread percentage says that you are going to be wrong. Even one filter, or one other edge such as seasonality is enough to turn a coin toss into a winning strategy. You may need big pockets though as your edge is likely to be small and your draw down periods big.
At the end of the day we are all managing risk rather than actually buying and selling stocks and shares in businesses. Never forget that the best manager of risk is your broker.
