Hey jcl,

I just got started learning about automated trading. I used 3dgs and because it shares the same forum I got interested about it and started reading the manual. I think I found some mistakes in the manual and wanted to post them here(didn't know where else smirk )

In "Zorro and the Brokers" -> "Observing your VPS trade status" -> last point: "the public IP address of your server - for instance, bei entering 98.765.43.12\Z12.htm in your browser's address field." -> "bei" should be "by"

In "Workshop 4" -> After "We're now going to analyze the code line by line" you cite the code twice, but with other values than in the initial code. "vars Trend = series(LowPass(Price,1000));" should be "vars Trend = series(LowPass(Price,500));"

Otherwise a really nice manual! Really easy to understand even for people that never had something to do with trading(like me).

I'm currently playing around with the basics, hopefully I can develop some own strategies on my own in the near future laugh

kind regards,

Alain

P.S: should we all continue posting into this thread when finding other mistakes or will you create a new Forum like you did for the 3dgs community?

Please proofread this page http://zorro-trader.com/manual/en/stop.htm

It says
Quote:
Entry
Enter the trade only when the price reaches a certain value at the next bar (default = 0 = enter at market). The value can be given either directly as an Ask price, or as a distance to the current close price. A positive price or distance constitutes an entry stop, a negative price or distance an entry limit. An entry limit buys when the price is at or worse than the limit; it increases the profit of the trade as it buys at a better price. An entry stop buys when the price is at or better than the limit; it reduces the profit, but enters only when the price moved in favourable direction, and thus acts as an additional trade filter. If the entry price is not reached within the allowed time period (set through EntryTime), the trade is cancelled and a "Missed Entry" message is printed to the log file.

The emphasized fragments are opposite to statements of those that appear here and here.

For one thing,
You say "An entry limit buys when the price is at or worse than the limit"
They say "Limit Entry orders ... enter the market at a more favorable price."

Ah, I see. "Worse" means that the price went down when your trade needs it to rise. The other website describes the same price move as "favorable" because it happened when the trade was not yet entered. Both is not wrong, but indeed confusing and I'll try to make this more clear in the manual.

Hi jcl. OK, I'll throw in a couple of minor things... laugh

On the Indicators page, TrueRange is out of alphabetical order. Also, the link to TrueRange in ATR seems to link to the description, not the header.

On the Trading page, the Progress Bar is described as "The left segment of the Progress Bar indicates the closed profit of the strategy since starting it, the right segment indicates the total profit or loss of all open trades (including phantom trades). When the right segment is green, your trades are in the profit zone; when the left segment is green, your account is in the profit zone. Otherwise the segment is red." A recent Demo strategy did 1 trade for $.64 profit. With that 1 trade closed and no open trades, the Progress Bar was left ~2/3 green and right ~1/3 red. Where did the red come from? With no open trades, shouldn't the right side have been 0, therefore non-existent, and hence the whole bar green?

Thanks.

Re: Entry
Some illustrations would really help here. There are at least 4 scenarios.
Entry is negative, next bar open is above |Entry|.
Entry is negative, next bar open is below |Entry|.
Entry is positive, next bar open is above |Entry|.
Entry is positive, next bar open is below |Entry|.

I have tried making zooming in to my plot. I have tried poring through the log. In complex cases, I have a hard time understanding what is happening, especially since in practice only entered trades are plotted. Missed entries, irrelevant stops, etc., are not plotted. Can you add visualizations at some level?

Hi jcl. How about an update of the Testing page to reflect the current result window display: <nnn> <mmm> <www>/<lll>. What are the <nnn> and <mmm>?

It's the current balance and the value of the open trades - that was indeed missing in the manual.
