not btc- usd but usd-btc...
so it will sell btc when usd get more in value ( decreasing btc price ) and buy when usd get lower ( increasing btc price ).
Then ema trading will work to generate more btc but also usd as you could always sell your "more" btc manual when you want usd...
So as for now usd is on a downtrend...
When btc drops usd is in uptrend...
When you buy and sell BTC for USD you should be trying to increase your USD balance. Buy BTC for low value in dollars, sell high for more dollars. Over the past week of micro-trading I've had to change my mentality. I started out trying to trade up .5 BTC to 1 full BTC and with the current volatility, I was on track. I caught myself halfway through the week - my BTC balance was not increasing as steadily as my USD balance was. In essence, when you trade on this current uptrend, you hope that the price of BTC will drop and you will be able to snap up lots of BTC to dump at for a better fiat price. As the trend goes up, I can buy fewer BTC at the high price, but my USD balance is increasing.
TL,DR - you're looking at the wrong charts if you want to trade for BTC balance. You need to be selling and buying USD on the BTC value.
Increasing your usd would make sense when btc in the longterm will decrease but btc in longterm only increase, so lowering you btc volume and increasing your usd volume is alsways losing value.
This would be ok with forex trading or some stock trading.
For BTC we must do it like btc is the main currency and we sell/buy usd on up/downtrends.
Like with default setting making 12000-13000 usd in the past 2y is increasing your usd *120 - *130 btc got worth 250* - 325* in that time, halving your btc volume just cost money...
When you traded in the same time as i said you would have made more btc and so also more usd...
Maybe it should just be an option in the bot to trade to btc-usd or usd-btc..
for me and the most others btc-usd don't make sense as you lose btc in longterm and so also usd ( even when usd volume increase ).
If you don't believe in BTC you could be ok with trading btc-usd.
If you believe in BTC your would trade usd-btc.
