Team Aphid,

I guess this question is not just for you but all veteran traders. When do u stop trading a strategy? lets say I use this bat or any other strategy for few months/years, and at sometime, it goes donwn 20%....or 25 or whatever....but how do u decide that a strategy is not effective anymore?

There is no correct answer to your question as it totally depends on any trader's risk profile. In our opinion, one should determine his/her maximum drawdown limit during a year such as 20%, 25% or 30%, then if the system you trade reaches that point any time during one year period, let's say between 1/1 and 31/12, you can cut off trading with that system for that year. Next year you should start trading with the same system because any mechanical system can produce negative results on annual basis. If the system goes bad for the second year in a row, then the trader should sit back and seriously consider about the system and he/she should determine what is going wrong and try to improve it according to changing market conditions if that is the main reason for failing.

I have a question for team aphid, as of right now, I am in a long for trade 1, now trade 2,3, and 4 are about to trigger(at 61.2 and 38 fib lines). the blue line has already surpassed original stop loss point, if I were to enter trade 2,3, and 4 now, would i still have my stop loss for them at a significant low +10 pips or should it be the bat line?

We guess your position is on GBPUSD. And we believe your swing low bar is at 04/16 09:00 bar, 1.9862 low. If this is the case your stop will be 1.9862 minus 10 pips, 1.9852. And you should have closed one lot (taken at 61.8 fib level on 04/16 14:00 bar) in profit (exit at 04/16 15:00 bar). Then you should have taken trade # 2,3 and 4 at 15:00 and 16:00 bars respectively. As of now, blue ATR line is at 1.9845 and your stop is at 1.9852. Whenever blue ATR line surpasses 1.9852 level, your new stop loss will be trailed by this blue ATR line. Until then, your stop will be at 1.9852.

Ok so just to confirm....lets say I entered trade 1 at 1.9800, stop loss 1.9750(significant low -10), then the pair retraces back to trigger trade 2, 3, and 4. but while triggering, the bat line has reached 1.9770. so while triggering trade 2,3, and 4, the stop loss would be 1.9770(and not 1.9750) even though its only few pips away from the entry point??

Thanks.

ATR line has always priority as a stoploss if and only if it is higher than significant low -10 and lower than significant high + 10. Therefore, SL in your example will be 1.9770.

Trying to livin up the thread here since its fallen off the first page i'm trying to come up with ways to determine when to enter when a either side of the court has the ball.
The idea here is the price passes through a blue/green BAT 8-12.7 and then buys are placed at all light blue/red BAT 300-2.0. The idea is, once priecmoves above 8-12.7Batline the bulls are in control. Now avoiding pulls you can buy when the bulls are ideally buying as well. Basically using the longer bat to determine who is in control, and the 300lightblue to pinpoint where the buying is happening again.
But i am having problems with the indicator, and i'm not sure if its native to the modified version i'm using(V2 with median closing etc) but sometimes price breaks the BAT line, but for some reason is not strong enough to force the indicator to draw the 2nd line. i've circled what i'm referring to. If there was a way to make a popup of when the indicator is saying its strong enough to force that 2nd line formation that would be sweet.
But i post my settings because it seems to work well, filtering out some bad trades visually. I just want more ideas/thoughts flowing on around here. Tell me what you think, maybe we can improve. or maybe my settings are stupid

BAT ATR V2 ATR PERIOD 8 FACTOR 12.7 = green and orange lines
BAT ATR V2 ATR PERIOD 300 FACTOR 2 = light blue and red lines

Hello, TeamAphid and thank you for sharing this beautiful method!

Quote main rules: "This re entry can only take place if the price stays within the boundary set by the 161.8 level"

Here is the situation on the chart. the shadow of the 1st candle hits 161.8 level. Have I to
- re enter @ Start level?
- enter @ 61.8 level?

Thank you!

If price hits 161.8 level, then you will not enter #2, 3 and 4 trades. So, you will hold only one lot and trail it with ATR line.

Thanks for your contribution. It is always possible to change parameters and possibilities are endless. If you think your parameters are working well, then the next step should be proper backtesting to see if they are really good. By doing so, you can feel how the indicator behaves in certain situations and solve many problems when you do have during visual backtesting.

Rave,

v2 default setting uses close to switch BAT line, while v1 uses High/Low, you can change CloseBase parameter.

any idea why you use 300 in 1H TF ?

I am thinking using ATR 2 and Factor 1, because of responsiveness.

Play with these indicators as well, I like to use M5 with compressed view to get the overall picture.

Hey guys, did anybody have this problem? when i try to backtest this strategy the indicator only shows up from fab 07 till today.....but not before that. I tried to get some help on other thread and here is the answer I got.....

QUOTE:

//---- indicator parameters
extern int BackPeriod = 1000;
extern int ATRPeriod = 3;
extern double Factor = 3;
extern bool TypicalPrice = false;

These are the first lines of the indicator. I see a Backperiod set to 1000. And as expected it did not go far. If you change this line in the indicator to let's say 10000 it will show you much more. Of course it is better to ask the creators of the indicator why they have this limitation. I understand that it will calculate faster. If this is the only concern of the creators then you can go and change it.
Regards

QUOTE END...

do you know why this is the case?

It was meant for performance, as this indicator is called from others (8TF,MTF), but unlike HAS, BAT didn't experience performance lag, so it is not necessary to use BackPeriod, change to 0 with this updated file, so you can have all bars painted.

Trying to livin up the thread here since its fallen off the first page i'm trying to come up with ways to determine when to enter when a either side of the court has the ball.
Here are my observations so far...

I did some extensive backtesting with something similar in mind except that I used 3 moving averages to define up-trend, down-trend, and range bound conditions. I took every trade the BAT indicator said to take then assigned a specific condition to each completed trade according to my indicators. It was a lot of work... Unfortunately, the results were not what I hoped for. No matter how I tried to define market conditions, by far my most profitable scenerio was to take each entry the BAT indicator said to.

Call me captain obvious here, but I think it's good to remind everyone that this is FAR from a "mechanical" system. It basically has only one mechanical component... Entry. The one element that has *substantially* impacted my profitability is the good ole' swing line, and placement of it is entirely discretionary. After a lot of practice with it profitability has dramatically improved. So, like many other systems practice is the key.

I will do some testing on years 2004-2005 GBPUSD and post results here in a day or two. it looks like Team aphid did their testing for year 2006.

Do you have any rules for placing it?
