I have backtested this AFL on banknifty from 1st to 22nd Aug 2013 on 5 minutes TF with some tweaks to the AFL.

There were a total of 32 buy/sell signals during the period.

15 have hit the target
12 have hit the Stop Loss
5 trades not triggered

Considering a total of 27 triggered trades, the AFL has experienced 55% hit rate with 1:2 risk reward ratio which is by all standards a good one. However we cannot conclude its effectiveness on basis of such narrow data periods.

The Tweaks done.

1. In case of buys, I have taken the high of the bar on which a buy is signalled and added one point to the high to trigger the trade. In case of sell signal I have subtracted 1 point from the low.

The AFL incorporating tweaks is produced below

Hi Tamil Trader,

In one of the posts, you said that we have to track yellow line for change of trend.

can u please explain a bit more on this.

see the yellow line in the chart...if the bar closes above the yellow line.. buy signal is generated...

if the bar closes below the yellow line.. sell signal is created. thats all..

no nee to place the stop loss near yellow... we should wait for bar closing.. then only signal will be changed

Hi experts

Can anyone write me a code for trailing stop loss? No more than 10 lines, I guess. Will pay Rs. 1000/-, but only after seeing the completed code in teamviewer. Sorry for this, but I have been cheated, twice in the last 2 weeks, of Rs. 4500/-, so am a bit cautious. Hope colleagues don't misunderstand me. you can pm me or write at sandip1952 of gmail. After this job, there will be 8-10 more, for improvement.

Ford that was most kind of you. May be I need to know to move around these posts, but how can I find your afl within the 20 odd pages of posts by you? Please help.

Also, as you have encouraged me, may I ask for guidance on the following?

1) my afl is putting 2 entry, or 2 exit signals next to each other. Like sell-sell, buy-buy, cover-cover, etc.. How can I fix this?
2) I don't want Candle Completion option as it almost always eats away profits in close situations. And Immediate is risky because signals come and go. How can I wait for 10 seconds to see if the signal has stayed put and then act?

Thanks again!
