Error action Error: Invalid get_ticker

[mistersms]

Hello,
i sometimes get error message "Error action Error: Invalid get_ticker"
is this an error from binance api or from the bot self?
i am using last binance-traderBot code with npm 5.6.0 and nodejs v8.11.2 on an debian 8.10
thx for support

maby i ran into solved issue #2 with old code in trader.js, now i changed code in trader.js to the new code in fixed issue #2
know i am testing.....

the newest version ov trader.js did not resolve my issue with Invalid get_ticker

i am using the following coin.js with quantity 0, so autocalc is used:

const coins = [
{
symbol:'ETHBTC',
quantity:0,
stop_loss:0,
mode:'profit',
profit:1.0,
increasing:0.00000001,
decreasing:0.00000001,
loop:0,
wait_time:1,
prints: 1,
},
{
symbol:'EOSBTC',
quantity:0,
stop_loss:0,
mode:'profit',
profit:1.0,
increasing:0.00000001,
decreasing:0.00000001,
loop:0,
wait_time:1,
prints: 1,
}
]

module.exports = coins;

thats the logging output, i am forwarding default output to an own log file like npm start >> logxxx
