I think the big money is made from focus for sure....but all in one is a bit too risky for me. Maybe 2. or 3.

"Trading one stock at a time is fine as long as you don'tput all your eggs in one basket. All it takes is for your stock to get halted once to find you just lost half your portfolio. If you are going to be so high risk it would be wise to hedge with a put option against a long position,IMO."

Perhaps you didn't see the TRADE PLANNER FILTER DISPLAY that I recently posted.

You define your risk BEFORE you enter the trade.

You are correct about trading HALTS.

Well it is going slow, I did do some work on method to get Optimal f value via Kelly formula and Backtesting results.


where PF= Profit factor = (gross profit)/(gross loss)
and P= probability of winning trade = (# winning trades)/(trades completed)

using the following code, able to find gross profit and gross loss from each trade's percentage gain/loss

gp=0; %gross profit
gl=0; %gross loss
for i=1:82
t=input('t?'); %trade gain or loss
t=t/100; %convert percent to decimal

After doing this for a particular backtest, I found
PF= gp/abs(gl)= (1603.51)/abs(-1192.83) = 1.34

I also found stockfetcher Reward/Risk ratio to be 1.34

Stockfetcher uses the following to calculate it.

Reward/Risk Ratio: StockFetcher currently uses a Reward/Risk ratio computed using the following method. First, compute the product of the number of winners and average gain of the winners. Next, compute the product of the number of losers and average loss of the losers. The reward/risk is computed by dividing the winner product by the losing product.

Will both calculations always yield the same results? Are they the same?
If not are they close enough to use Reward/Risk Ratio as short cut?

Continuing with calculation:

Portion of portfolio to risk on single trade for the particular strategy

= .23

Note: number of winning trades was 46, total completed trades 82
