Lol;
You are absolutely right...confidence in your system is the key.
Honestly, the bloody thing (futures trading method) gives me quite many losses... to a point where I start doubting the weeks profitability. The system takes me to unbearable bends before the law of averages kicks in. What keeps me going is the 100% confidence that when the profits come in, I will have no complaints.
The key is to take trading in packets of 20 trades. No rule or thought process should change in a given packet. When those 20 trades are over one could analyse and do the needed alteration. And then take up a new packet. Most importantly, a new trader must set risk amount per trade such that he can last on several such packets.
Soon, there comes a time, when no major alteration is required... and the odds are now in your favor.
