Yes, that's because of very small target of 10 Points in Nifty which is highly possible. 10 points a day would be fair enough if traded with more of no lots.

Once i get the corrected afl from happy, will backtest it with 6 years of data and need to check max draw down. ifs its reasonable, will make this as my adds to my current system.

80% is good success ratio... :thumb::thumb:
I suppose the success rate is 80% because profit is quickly taken. Say the profit is taken at 10 points... then around 3 points will go in expenses... this leaves us with 7 points in hand.

This get further reduced because real time execution will be less efficient due to errors and slippages.

Yeah, right. Just experimenting with 10 points, after the breakout there is a higher probability to make 10 to 15 points, if we have a target of 15 points, with slippage and commission we could reduce 5 points per trade which would result in 10 points profit.

I am sure you will leave no stone unturned in your research.

Just a suggestion. Do not aim for a high Strike Rate. That approach mostly leads to dead ends. A SR of 50% or little higher is usually a sign of a very good system in the making.

If the target is small, then is there a need to restrict the system to ORB? You could trade any breakout for that target.

My aim while trading ORB was to capture the big move, without having to watch quotes all the time.

But please do go ahead with your tests. You are sure to find something better :)

Sure Amit. As am much comfortable with Super Trend system which has a SR of only 42% .

am looking for another intraday based system to diversify my position, instead of adding few more lots to existing system i wanna try out with ORB intraday system for the following reasons.

1.To avoid gap up/down
2. No carry over/ No over night news impact.
3. After all, I have the knowledge of ORB system, where without afl i can trade it with just charts.

Just wanna experiment with 2 systems.

One with Super Trend where irrespective of any news events/whatever, everything will be already factored in the charts. So i will be in the trade all the time.

Anther one with ORB intraday system, where in case of false signals with Super Trend, i can compensate it by trading ORB system.(If 10 points target is achievable) with less draw down.

maybe just too good to be true :)


Thanks Happy.

I checked it and i could see 80% of total trades achieved the target. With the present AFL, the entry and stop loss condition varies completely.

Could you please help out in implementing the below conditions.

1. After breakout of 5 Mins bar, the position needs to be exited once the Target of 10 points is reached.

2. Stop loss is when 5 mins bar closes above/below the opening range. (i.e. above/below 1st 5 mins bar)
Use the code i posted on Amibroker help thread i.e. 10 points target and 10 points stop

Now we can see the 80% come down to 50-55% . . .


but we will still test the SL of close on the other side of ORB . . .


:) Happy

Looks like Augubhai has already coded for reversal/stop on first bar's breach

check the following code . .

ORBHSL = ORBH * (1-(SLPct/100));
//ORBHSL = ORBL;
ORBLSL = ORBL * (1+(SLPct/100));
//ORBLSL = ORBH;

just reversing the commented lines should change the SL . . .

//ORBHSL = ORBH * (1-(SLPct/100));
ORBHSL = ORBL;
//ORBLSL = ORBL * (1+(SLPct/100));
ORBLSL = ORBH;


for profit target he is using % so for 15 points it will be 0,25%



Code:
function ParamOptimize( pname, defaultval, minv, maxv, step )
{
return Optimize( pname,
Param( pname, defaultval, minv, maxv, step ),

check the following code . .
Sorry guys... it's a long time since i had written that code, and do not remember the scenarios that i had covered. Else, i would have let u know about it earlier.

Just one warning - that afl is not perfect. It's buggy, and there are scenarios where it misbehaves. I remember that i had tried to add TSL to the code, but it did not work correctly. It might make sense to visually sample the results after u run the code.

My original backtest of the ORB system was in perlscript, but I do not have that code now.... it might in some of my old computer backups, though. In those test, I had covered an extensive number of scenarios, including the one being discussed. The results for Nifty (as far as I remember) were:
Best settings: Enter on ORB at the earliest (i had only 5 min data... so 5 min). No SL. Close at EOD (these were the most profitable parameters)
Second Best: Enter ORB at the earliest. On entry update the other order with SL 0.6% from entry. Close EOD if SL not hit.
Third Prize: Enter ORB at the earliest. On entry update the other order with SL 1.4% from entry. Close EOD if SL not hit.

Data for the test was of 2007-08.

Agree with most of your findings . . . .

My conclusions after testing ORB thoroughly on a previous occasion were ..

Fully Accept the uncertainty of the intraday moves and enjoy the fruits :D

Case in Study: Last 2 days . . .

Will just convert your code to accept points instead of % for profit and post it again . . .

So that those who want to run the tests can do it :thumb:
