Scalper Buys/Sell Replica

Recommended Posts

Hi All,

 

I have been an avid reader of this forum for a while. I just thought I would contribute to an internet that I have taken so much from...

 

Here is a replica of Scalper Buys and Sells. As far as I can tell, it matches up perfectly. If you would like to use it along with the Heiken-Ashi paintbars, I recommend you set the plot thickness to at least two more than the thickness of the Heiken-Ashi (In the attached picture, the Scalper Indicator is set to 3 and the Heiken-Ashi is set to 1). Also, please note that candlesticks are not supported.

 

Bugs/feedback are appreciated. I hope you all enjoy. Happy Trading,

 

Luis

 

p.s. For those of you who like to use candlesticks, I also have a ShowMe version, which places a dot on the highs/lows...Let me know if there is interest.

You are all very welcome :) Glad I could help.

 

Glenbee, I will be posting the ShowMe in a separate thread shortly.

 

As far as how the indicator actually works, John's description of "three higher closes" is a bit misleading. I disregarded this criteria in the code. It is merely based on swing highs/lows. I'll give an example for a Scalper Sell:

 

1. You get a high that's at least as high or higher than the previous two bars. This bar is a potential paintbar.

2. The next bar makes a lower high; The low of this bar is the trigger.

3. From here, if we do not make a higher high and we get a close below the trigger, we paint the swing high bar. Concept is simple but was a bit tricky to program (for me, at least).

 

By the way, I got this description from the following video:

Hope it helps!

I've been searching for this indicator for literally a month now. There are some similar .eld's floating around, but they are not identical to the Scalper indicator. Yours is. Thanks so much!!!

Could you please post the source code so I could port it to Amibroker?

Thanks!

Hi Trader Lu, Thanks for the code it works in 2000i with some modification. However, the white paint bar completely blots out the colour of the underlying heiken ashi colour (unlike your attached thubnail). I have tried changing the thickness of both the HA and scalper b/s but still get just a white bar.... any suggestions ?

 

Thanks

Traderlu has also kindfully done it in a "show me" edition, shown here:

Try transferring your code into a "Show me" indicator.

 

Cheers

Dovetree,

 

I have had that same problem. I think it has to do with the order in which you add the analysis techniques to your chart. Try adding the Heiken-Ashi first, then the Scalper, or vice-versa. I can't remember which was the right order. Just don't add them at the same time. This should do the trick. And don't forget the thickness! Hope this helps

Hope I'm not out of line here...but I use Sierra charts and the code that they use is C++. Does anyone know how difficult is it to convert code like Traderlu posted to C++. Does anyone have experience doing this or are there any examples of how to convert TS code to C++?:confused: Thx

i do not know where to start from.

do u?

 

There's a link on page two of this thread. The TradeStation code is posted there. To start I would have a look at it to get the logic behind the paintbar study. If you don't know any EasyLanguage then I'd take that code to a forum where people know esignal language. I personally don't because I can't stand esignal.

Good luck with your quest. I hope you find answers.

Traderlu,

 

Hi. Thanks for posting the TS code. I tried following the code, but I'm and esignal person so I don't get the small nuances of the code. I'm trying to convert this to esignal, but I keep getting confused by the rules. The video is also confusing as Carter keeps correcting himself and isn't clear.

 

1. You get a high that's at least as high or higher than the previous two bars. This bar is a potential paintbar.

Q- Is this 3 higher highs based on the close of each bar or just the highs of each bar?

 

2. The next bar makes a lower high; The low of this bar is the trigger.

Q - Same question as before, is this lower high based on the close of the trigger bar or the high of the trigger bar?

 

 

As far as how the indicator actually works, John's description of "three higher closes" is a bit misleading. I disregarded this criteria in the code. It is merely based on swing highs/lows. I'll give an example for a Scalper Sell:

 

1. You get a high that's at least as high or higher than the previous two bars. This bar is a potential paintbar.

2. The next bar makes a lower high; The low of this bar is the trigger.

3. From here, if we do not make a higher high and we get a close below the trigger, we paint the swing high bar. Concept is simple but was a bit tricky to program (for me, at least).

 

Thanks.

    • Good news!  (and greatly under-reported, btw) -- Flu(s) and pneumonia(s) may have been eradicated.  No deaths from either in months and months.  Thanks god.
    • GOLD SUFFERS MILD DECLINE FOLLOWING GROWING US-CHINA TENSIONS Gold (XAU/USD) dipped in the early Asia trading session on Monday as growing US-China tensions continue to influence demand on the safe-haven asset. Gold futures shed about 0.47% reaching a low of $1,724 just a few hours ago. The precious metal failed to hold on to its gains from last week’s session. Stocks, which are generally expected to move in the opposite direction of gold, were trapped in a bout of uncertainty with Chinese stocks suffering serious losses at the open of the session. According to reports, investors’ risk sentiment declined following China’s decision to formally table national security laws for Hong Kong and Macau as the National People’s Congress opened on Friday. This announcement caused citizens of Hong Kong to take to the streets in protest on Sunday. The protesters were met with heavy resistance from the police who fired water cannons to disperse them. The tension between the world powers escalated after Chinese Foreign Minister, Wang Yi, said on Sunday night that the US was nearing a ”new Cold War” with China following President Trump’s threat of ‘strong action’ should the proposed law be enacted. This threat was followed by the US Commerce Department blacklisting 33 Chinese entities on Friday. XAUUSD – Daily Chart Gold (XAU) Value Forecast — May 25 XAU/USD Major Bias: Bullish Supply Levels: $1,745, $1,763, and $1,797 Demand Levels: $1,722, $1,717, and $1,700 The XAU/USD was met with a soft decline to the $1,720’s level as projected last week. Gold has resumed on its upwards move to the anticipated $1,740 level. However, gold has to stay above $1,722 to confirm its bullish momentum. A break below that level could send the price down to $1,700 – $1,695 levels rapidly. Overall such reality seems very unlikely for gold in the time being.   Source: https://learn2.trade 
    • USD/JPY CONSOLIDATES BELOW LEVEL 108, BREAKOUT LIKELY Key Resistance Levels: 111.000, 112.000, 113.000 Key Support Levels: 104.000, 103.000, 102.000 USD/JPY Price Long-term Trend: Ranging The pair is currently in a sideways move between the levels of 110 and 108. The Yen was in an uptrend but it is facing resistance at level 108. The pair is on a downward move as a result of the resistance at level 108. The Yen may reach a low of level 106 if the selling pressure continues. USD/JPY – Daily Chart Daily Chart Indicators Reading: The 21-day SMA and 50-day SMA are sloping horizontally indicating the sideways move. The Yen is currently at level 51 of the daily Relative Strength Index. The Japanese Yen is still in the uptrend zone and above the centerline 50. The market is currently falling after resistance. USD/JPY Medium-term Trend: Bullish The USD/JPY pair is trading in a bear market. Recently, the Yen moved up but was resisted twice at level 108. On May 14, A bullish candle body tested the 0.382 Fibonacci Retracement level. As the bullish candlestick tested the 0.382 retracements, the Yen will fall and reverse at 1.618 extension level. This is equivalent to level 106. USD/JPY – 4 Hour Chart 4-hour Chart Indicators Reading The pair is below 80% range of the daily stochastic. This implies that the market is in a bearish market. This is a confirmation to the price action which is indicating bearish signals. The SMAs are also sloping upward indicating the upward move. General Outlook for USD/JPY The Japanese Yen is currently in a downward  move after falling from level 108. The market will fall to level 106.800 but if the selling pressure persists, the pair will reach the low of 106. Alternatively, the price will consolidates below level 108 for a breakout.
