In simple words...
Throw in more money in to the trade which is opened. This allows to average up or down a specific trade you are in. Meaning if you have a deal with 100$ on BTC/USDT and your current status is -10% on this deal.. You can add another 100$ to the deal and it will average down your loses to -5% on this specific trade. This will allow you to shorten your trade time, but it will also cause you to have more risk if the market still continues to go down ward you may need to buy in a little more, or wait untill the market turns back up. Buy in should never be used with all your capital it always has to be used in sense that you know the risks that market can go down more, or even lot's of more red candles to come. So you should always consider using it knowing your risks that you can take, and the market odds of up or down movement.

How ever Buy in is a smart way to enter step by step in the market seeing that the market is ready to finally start moving upwards.

Buy in ratio or coeficient.
Ratio is the strenght of averaging... The same 100$ with -10% on BTC / USDT..
If ratio is 1 it will use full averaging strenght.

If ratio is 0.50 it will average down only half of your buy in funds. so if you added 100$ to a 100$ trade which is -10% your new status will be not -5% but -7.5%

Changing the ratio to 0.25, 0.5, or 0.75 will give you a chance to get a higher target. So if you use ratio 0.5 you will get -7.5% but the trader platform will keep in mind that your real averaging price is -5%, so when your target will be reached you will have +2.5% more in target than it is showing. This is a nice way to buy in more and more with lower ratios dus when the target is reached you will have more % procent, but keep in mind this will increase your risks, and it will increase your trade time!


Always be sure of your risks, always trade safely, and nor we no anyone else cannot tell you what to do. Be aware of your own decisions!
