how to launch it, not launching with a server

I'm trying to figure out what exactly this error is referring to. I'm playing around with a small amount of money (around $10 USD worth) to test the waters, and when the uptrend hits the threshold, it attempts to sell for profit, however it also returns the above error.

**php7.4 bots/uptrendsurfer.php -p BTC-USD -bw 10 -g 0.1 -nib
[i] Trading BTC-USD
[i] Will buy 10 USD in BTC
[i] Will sell when BTC will gain 0.1%, meaning when it's worth 10.01 USD

Any insight of how I can correct this?

When starting bot:

PHP Notice: Undefined index: message in /home/pi/cryptotrader-master/gdax.php on line 230

This errors keep coming up.

Is it possible to have webhook for notification or an web dashboard simple with a short log or a graph with profit or lose

php bots/waverider.php -p XLM-USD -bw 40 -g 10 -pv 5
[i] Trading XLM-USD
[i] Will buy 40 USD in XLM
[i] Will sell when XLM will gain 10%, meaning when it's worth 44 USD
[i] After selling I will wait for XLM to drop by 5% before re-buying

====== BOT STARTING ======

[i] 40 USD currently is 141.2354572 XLM
[!] Buying 141.2354572 XLM!
[X] Error while making a call. Message: size is too accurate. Smallest unit is 1.00000000

I have a different bot running with BTC-USD and it was able to execute fine, but when I tried to use XLM, I receive this error message.

Hello Haschek,

I was wondering if there's any way or chance to get this to run through a webhook for Discord? I've tried creating my own but I'm having a lot of issues, any integration or instructions would be massively appreciated,

Hello,

What is the best way to restart the bot after say a power outage or an accidental ctrl+c?

I ask because when the bot starts it buys the requested amount of BTC but if a computer or bot restart is required it no longer has sufficient funds for purchasing. Currently I am manually selling once profitable and then restarting the bot.

And Thank You for sharing your hard work.

Hello,
i just tried to run command php /home/pi/cryptotrader/examples/account_info.php
but i get the following error :
PHP Fatal error: Call to undefined function curl_init() in /home/pi/cryptotrader/gdax.php on line 197

Could you please help me?
Regards

Hi Christian,
first of all thanks for your work.
I am experiencing some issue in getting account info when calling function makeRequest that returns "Error getting accounts".
I guess it could be some problem with CURLOPT_URL but i am not php expert.

I keep getting this message when starting the bot:

Api details have been put into config.inc.php correctly. Have tried creating new API key on GDAX but no success. Any clues?

UPDATE: nevermind I solved it! I was replacing the labels with the actual key data inside config.inc.php oops.

Example of waverider uses call to uptrendsurfer

Hello!
I'm trying to figure out how the fip value works. I have bought 0.21189432 ETH for 228 € when it's price was 1074.30€. Is this the right command to run?

php bots/waverider.php -p ETH-EUR -bw 228 -g 10 -pv 5 -nib fip 1074.30

Thank you!

Hi Christian,

I am currently running the cryptotrader and I do really admire you for being able to put such nice little app in place.

I am, however, wondering whether you could help with the following: When I run the script, I receive the following error-messages:

PHP Notice: Undefined index: message in /home/pi/cryptotrader/gdax.php on line 230
PHP Notice: Undefined property: gdax::$lowestask in /home/pi/cryptotrader/gdax.php on line 53
PHP Notice: Undefined property: gdax::$highestbid in /home/pi/cryptotrader/gdax.php on line 55
PHP Notice: Undefined index: message in /home/pi/cryptotrader/gdax.php on line 230

Can you help to resolve this?

The script runs on a RPi3 with php5.

Looking forward to hearing from you. Greetings to AUT.

Cheers,
Daniel

Hello,

I saw your previous bots projects and thats how I found this one. I cloned everthing onto my Raspberry but I am now just wondering how to I set up buy and sell points? In the previous bot your wrote you mentioned that, in this one I am not able to locate that.

Thanks for your help!

First, I want to thank you for this great project!

My question is about the rebuying function. How does it work? When you say, waits for a drop, and then rebuy what quantity?

In the example command:

# Example usage: Buy 100 USD worth of BTC, sell when it gained 10% in value and re-buy when the BTC price drops by 5%
php bots/uptrendsurfer.php -p BTC-USD -bw 100 -g 10 -pv 5

When the prize drops over a 5%, then the bot rebuys, right? How much? 100USD again?

Thank you in advance.

Thanks to all who have contributed to the update 2020 / Coinbase Pro. Very well done.

One question though:

The scripts run very well under macOS (php 7.3.11). They do however not run under Raspbian (php 7.3.19). The output is as follows:

WAVERIDER:
pi@raspberrypi:~/cryptotrader-master $ php bots/waverider.php -p ETH-EUR -bw 100 -g 10 -pv 5 -nib -sim

SIMULATION MODE

[i] Trading ETH-EUR
[i] Will buy 100 EUR in ETH
[i] Will sell when ETH will gain 10%, meaning when it's worth 110 EUR
[i] After selling I will wait for ETH to drop by 5% before re-buying

[X] Error getting products
[X] Error while making a call. Message: Rate limit exceeded. For rate limit information see https://docs.gdax.com/#rate-limits

Hello, again, thanks to your great work, i use your bot and it's simple and all i need,
if i can help i will do it with pleasure :-)

i see this error when i run this beautiful bot :-)

the docs say :

Rate Limits
When a rate limit is exceeded, a status of 429 Too Many Requests will be returned.

REST API
PUBLIC ENDPOINTS
We throttle public endpoints by IP: 3 requests per second, up to 6 requests per second in bursts.

PRIVATE ENDPOINTS
We throttle private endpoints by user ID: 5 requests per second, up to 10 requests per second in bursts.

FINANCIAL INFORMATION EXCHANGE API
The FIX API throttles each command type (eg.: NewOrderSingle, OrderCancelRequest) to 50 commands per second.

Perhaps can we set the bot to follow the numbers of request ?
