ORB System for Amibroker (AFL)
this is a simple intraday ORB system. ORB stands for Opening range break-out.
We decide on a period to watch – it could be the first 5, 10, 15, 30, 60 minutes – anything that you decide. Assuming that we decide that the opening range period is 10 minutes. At the end of 10 minutes, place a Buy Stop Loss order at the day’s high(filter), and a Sell Stop Loss order at the day’s low(filter). The filter need not be a big number, otherwise you could lose some part of a good move.
If the Buy Stop Loss gets triggered, you could either decide to leave the the Sell Stop Loss unchanged or modify it to a fixed percentage or a trailing Stop Loss. It is up to you to decide on the stock, filter, and method of Stop Loss once you are in position.
The premise is that we make the most profits during trending days. Generally, on trending days, the Open and Close are at near the extreme ends of the daily range, with minor pullbacks. So once you are in position, if you set your Stop Loss to avoid pullbacks, then you would get the most of a trending day with less risk. The key here is to decide on the Stop Loss. The Stop Loss will vary from stock to stock and period to period. The AFL will help you backtest and decide on the Stop Loss.
With whatever backtest I have done, the maximum returns were when there was no stop loss. Obviously, that is more risky, and I never trade without a Stop Loss.
This is not something new that I discovered. You will find so many ORB systems on the internet. What I want to share is that I have been profitably trading this system successfully for many years now – on NIFTY and recently on Bank Nifty. (Sometimes there have also been very serious whipsaws as well).
This is an Intraday method that does not require any charts. You just need to know the day’s high and low at the end of the opening range period. You also do not need any AFL, except for backtesting.

Well, this is a good system with discipline in built into trading. What is also important is to understand what kind of a trading that will be presented which can only be said after looking at first 1 hour of trade.one can use this system along with Market profile or VWAP & its band to see what kind of a day is developing, i am happy to know that you are getting good results and i believe is that you use your experience and mixing the market sentiment along with this trading system.All the best.
Nice afl
Very good AFL. You are able to modify by various time period for good result
