The older formulas for expectancy have been phased out. The formulas given in the previous books of Tharp have been nullified by him in his last book. The latest formula divides the number obtained by previous formula by the average risk per trade, which is assumed to be equal to 1 R.
And if the risk per trade is unknown, the std deviation can be massive, driving down the SQN number into a much smaller range, making it unviable to apply position sizing techniques to such a system.
The same goes towards High R Multiple profits
And if the number of trades is kept to 50 for calculating SQN , its better. And the trades that you assume as your samples, should have a mix of all 6 types of markets. And if you dont have that in continuous form, like the mkts are trending for 2 months, then you need to take another 50 trades from a non volatile sideways range, and calculate the expectancy and std dvn and the SQN number for that kind of market

further development as i am waiting for another guy to code the open types and is a separate project by itself. merging this and that will make it a mammoth project by itself...
One unknown factor is the sgx rule as i cant find a source for sgx historical IEOD data.
so far system has provision of carry over of 50% of positions only if certain conditions are met.
I am looking into the flow traders methods to see if the add on rules they follow is better than my 3 min addon...
I wish i had more helping hands on this project but most traders are already happy with their systems and some of the strugglers just want to make money and dont focus on trade logic anyway.
I have already mentions the trade logic in this thread and yet to see anyone join the dots to complete the picture... everyone is waiting for the afl... and they wont get it till i finish the rules... Its sad...! but i cant help it...!
