@lemondew, just to add to what ST da has mentioned, the risk %age for a given trade depends solely on the market condition and volatility when the trade is initiated right?. The max risk per trade for our strategy is just a reference value based on our historical back-testing and does not mean we should take max risk on each of our trades.
Regarding the number of trades per day it depends on the strategy you are following, if their is a trade signal one should always take it else it will become discretionary and not systematic.
If you get a chance and are interested try studying the trade logs on Madan's blogpost. He has been kind enough to share all the information online and if you ask me the data is enough to give a deep insight into how a professional trader executes his trades.
Its not correct of me to give the details as Madan would be the right person to talk about it, but I can give you some hits that you can learn.
1. It is not that trading for the day is stopped after 1 or 2 trades and any new signals generated later are skipped. Rather the strategy is designed such that it generates max 1 or 2 trades per day on average and all trades are taken if trade signal is generated. Understand the difference.
2. Further, If you want to know the holy grail, study the data little more deeply, there is a unique factor in his trading style and it is not just the strategy edge, position sizing, Risk/Money management or psychology.. know it and you will be enlightened...
