# Larry Williams "Pro-Go" Indicator for ThinkorSwim

This script is based on the Pro-Go indicator that Larry Williams came up with.

The formula is fairly simple.

Close - Open = Professionals
Previous' Close - Open = Novices

He then averages out with a simple moving average (length of 14).

Code:
``````# Larry Williams Pro-Go

declare lower;

input averageLength = 14;
input paintbar = no;

def public = close[1] - open;
def pro =  close - open;

def avg_public = simpleMovingAvg(public, averageLength);
def avg_pro = simpleMovingAvg(pro, averageLength);
def res = avg_pro - avg_public;
def priceSMA = simpleMovingAvg(close, averageLength);

plot pu = avg_public;
plot pr = avg_pro;

pu.AssignValueColor(color.red);
pr.AssignValueColor(color.green);

def condition1 = pu > pr;

assignPriceColor(if paintbar and condition1 then color.red else if paintbar and !condition1 then color.green else color.current);``````

@BenTen thanks for sharing. Res and priceSMA don’t seem to be used. We’re they intended to be used?

@barbaros Good point. I'm not sure either. I just converted it from the original code on TradingView.

Here is my attempt...

I love L Williams stuff. I have on my to do list to recreate the COT report for TOS since he constantly references it in his books

Larry Williams has a professional vs public buying called ProGo. Would anyone be able to convert the TradeStation code below:

So I have a quick question the Pro Go indicator is set to (14) but at times it would give an early signal then cross back down or above. I wanted to know is there a good parameter o can set it to. Like (30), (50) (100) etc that would be good for time frames of 5day 1-4 hours, 20Day 1-4 hour, 30day 1-4 hours or 3months 1Day or 1month 1day?

I use it with STD (Stabdard deviation channel) because I noticed that too but do you have something that’s a good trigger for 1M 1D chart. I use STD for support and resistance and now I just need a trigger to let me know when I should enter per timing. But it’s like nothing works can someone help me with a good oscillator or w.e because pro go alone is not working. I can use what yours but will it work with STD?
Use an RSI with the Pro-Go.

Use an RSI with the Pro-Go.
how didn’t I think of that the whole time. Also for the daily chart keep the standard parameters for the RSI (14)?

Or use MACD---Stochastics......something you can look at and instantly understand what's taking place, an instant confirmation. look at a bigger picture first, weekly......

I have watched Jake Bernstein use 57 on the Daily

I'm sorry. I still hang with the ol geezers like myself. He has done stocks and futures for decades.

He is one of the first to use Seasonals to identify trends.

Chris Moody did many of his indicators at one time (i dont think they work together any more) but I cannot complain about his analysis.

He is old, but he is the last of men with integrity-imho.

I have not heard much criticism about him, but I am always open. He has not compromised like the others trying to get rich before they die off. i.e. men like Pesavento moving from harmonics to Jean Dixon style analysis.

He is going to be doing another Wealth Charts 365 coming up. I most definitely dont promote Wealth Charts having tried the Hoffman platform, but Jake shows trades he is going to take in the future. So you can look for that.

He also wrote a book called Cycles of proﬁt that you can look for. Interesting book that covers the repeat of cycles.

If you use TradingView, he has an indicator you can use for free . Type in Jake Bernstein.

His seasonal website is https://seasonaltrader.com/contact.aspx

He has a free one month trial. I am not affiliated with him in any way, shape or form. I have always benefited from his research.

One thing for sure is this...When I used the 57 on the 6-month daily, it clearly provided when dips should get bought and when rips should get sold, as when an appropriate oscillator is used in conjunction.

Okay but what would the parameters be if I use a 1month 1 day chart and which oscillator should be used?

I'm no longer using small timeframes to trade with so I would not know.

wait 1month and 1day is a small time frame? i mean 3month 1day is fine too but its just a projection of 3 months time horizon and just 1 day of candle movement

I meant to say that I am not using anything less than 6 months.
