It took fairly a little bit of considering, however right here is the way you arrive at a “purchase immediately” or “promote immediately” value.
Let’s imagine you might have purchase orders:
- purchase 100LTC at 5BTC
- purchase 50LTC at 4BTC
- purchase 200LTC at 3BTC
And promote orders:
- promote 100LTC at 6BTC
- promote 500LTC at 7BTC
- promote 100LTC at 8BTC
and so forth.
We will acquire so much from this easy set of orders. For one, the market depth chart turns into very helpful when taking a look at this knowledge. So, you can say that the market unfold is 1BTC on this case, as a result of purchase and promote orders are separated by 1BTC
Now, shall we say we have now 125LTC we wish to promote. The best way you’d choose the very best promote on the spot value is to have a look at the purchase orders. Appears like you can promote your first 100LTC at 5BTC and the remaining 25LTC at 4BTC. So, 5BTC needs to be your max price. Relying on the API you might be utilizing, you may wish to place two separate orders at completely different costs or place one with the max value assumed.
It really works the identical method with shopping for. IF you wish to purchase 650LTC, you’d be capable to purchase the primary 100LTC at 6BTC, after which the subsequent 500LTC at 7BTC and the final 50LTC at 8BTC. So, your max value could be 8BTC. Though your precise value would fluctuate quite a bit. It is dependent upon what service and API you are utilizing as to the best way to finest place such an order spanning costs.
For Cryptsy you’d place such a purchase order as only one order of 650LTC at 8BTC. Crypsty robotically chooses the very best value for you, so you’d have this impact. Nevertheless, it isn’t assured to work this manner. When you obtained the order record, and somebody was to purchase up 50BTC at 6BTC, then your anticipated value would find yourself being fallacious. If you would like a value assure, you must place actual matching orders to the order e book. Following this technique although, you might have a excessive likelyhood of an order not finishing as properly, or taking longer than anticipated, similar to for those who purchase 100LTC at 6BTC, however somebody purchased 50LTC already. Crypsty by default would wait some time earlier than finishing the partial order. (assuming no different promote orders have been positioned at that value)
It is really a extremely easy idea, but it surely took me just a few days to really wrap my head round it for some cause. Hopefully if different individuals have the identical drawback, perhaps this publish will clear issues up for them
